Server + Ruby on Rails - Chromebook vs Raspberry Pi 4 ???
Thank you in advance for your help!
I want to install Ubuntu Server + Ruby on Rails.
Would a Chromebook or Raspberry Pi 4 be a better inexpensive platform for this?

[ubuntu] fan always working
I updated my Ubuntu to 19.10. Since then, every 40 seconds the fan starts working for 5 seconds and stops. This happens after I start a X session, even if I have no application started. Doesn't happen if I only login in the console.
I use Cinnamon. The top command shows the cinnamon process is using around 3% of CPU. Sometimes goes to 10% of the CPU. But doesn't seem to be related with the fan.
The sensors command shows that the temperature is always rising above 50°C immediatly before the fan starts working:
$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +53.0°C (high = +100.0°C, crit = +100.0°C)
Core 0: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 1: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 2: +49.0°C (high = +100.0°C, crit = +100.0°C)
Core 3: +49.0°C (high = +100.0°C, crit = +100.0°C)
Since then, I tried other window managers. The problem persists, but with different times. The given values are average, and not very precise, but the fan always starting working at regular intervals:
xfce: 90 seconds
Gnome and Unity: 180 seconds
I also tried a live usb installation to boot in Ubuntu 18.04, similar to what I had before the update. The fan problem didn't happen, and the sensors command shows that the temperatures never rises above 40°C.
This is very annoying because I always expect the computer to be quiet when it is not doing any intensive processing. Please tell if you need any more information to help diagnose and solve this problem.

Can't change SATA mode from optane
I bought a laptop which has this ssd https://www.westerndigital.com/produ...s/pc-sn520-ssd
bios sata mode is set to Optane without raid, and Ubuntu installer doesn't detect the ssd. I've searched in Google and you have to change the mode in BIOS but i cant do so. I've also read that you can change it in windows 10 but I didn't really understand how, could someone help me? Thanks in advance.

PAC7302 Camera Drivers & Software
Our college has a number of digital microscopes and endoscopes that use PAC7302 sensors. Although based on old technology these instruments are fairly new and we don't want (and can't afford) to replace them.
We are looking to use these on Ubuntu 18.04 LTS and Kubuntu 19.10. I have read elsewhere that GSPCA supports PAC7302 but references look out of date.
Can anyone recommend drivers and a good software application that would be best for this class of device and application?

Bugged default drivers for Radeon HD 6650M in 18.04 LTS. What to do next?
Hola good folks,
So, I have a laptop with...
Well... the default drivers that ship with Ubuntu (Kubuntu, actually) 18.04 LTS are pretty bugged for this system. Near as I can tell, the drivers for the dGPU don't properly support OpenGL somewhere around OpenGL 3.1 and up. This is most reproducible with Blender, wherever I invoke the Eevee render, as this requires OpenGL 3.3+ to work properly.
If it was *JUST* 3D, I wouldn't have too much problems with it, but there are also issues with the desktop environment. Window frames will sometimes get flickering ghost images of what's under them when they are moved (broken transparency), or disappear entirely. With MPV player (Probably also using OpenGL) if I pause the video, or rapidly minimize/maximize the window, the video gets stuck in a short , flickery loop. Sometimes this will cause the backdrop to go all black too. If I do enough screwing around, eventually the graphical problems will get to the point of making the desktop unrecognizable, unstable, and I am left with no choice but to restart.
Here is some more details.
Some other notes, in order of preference.
The reason I'm here is that I'm not really sure what to do about this? On the one hand, everything seems to be using the best available option. On the other hand, it's not working right. Is this a Mesa problem, a r600g problem, or a kernel module problem? The fglrx.ko module possibly (probably) has the correct firmware, but that's depreciated since Kernel version 4.4, and I'm on 4.15. How do I even work with this? Do I need to switch distros/versions? Or is that even going to work? Can I shoehorn in fglrx.ko? Or is that even going to work? Is this a known problem, and a fix is on the way? Will there even be a fix? Do I have to just live with this?
:confused:
I'd like to at least get the dedicated GPU working 100%. Worst case, seems like I (a) switch distros to use an older kernel, (b) disable the iGPU/switchable graphics, and (c) take the power usage hit. I *REALLY* don't want to have to do this . . .
So, I have a laptop with...
- CPU ---- Intel Core i3-2310m (Sandybridge Mobile)
- iGPU --- Intel HD Graphics 3000 (Sandybridge Mobile)
- dGPU -- Radeon HD 6650M (TeraScale 2 (VLIW5) "Evergreen" - Northern Islands)
Well... the default drivers that ship with Ubuntu (Kubuntu, actually) 18.04 LTS are pretty bugged for this system. Near as I can tell, the drivers for the dGPU don't properly support OpenGL somewhere around OpenGL 3.1 and up.

Sometimes this will cause the backdrop to go all black too. If I do enough screwing around, eventually the graphical problems will get to the point of making the desktop unrecognizable, unstable, and I am left with no choice but to restart.
Here is some more details.
- The package that seems to be supplying my drivers is Mesa (v19.0.8). (This is just userland OpenGL though, right?)
- The actual 3D driver is r600g, which should be correct for the TeraScale 2 - Northern Islands. (Mesa matrix decoder ring doesn't find the "HD 6650m", but does find the "HD 6650" as r600g/TeraScale 2)
- Command "lspci" lists my GPU as [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff) (For a time, I believe this was showing up as TURKS, not Whistler. Hopefully that means it's being worked on!?)
- Command "lsmod" lists the Kernel module as "radeon"
- "modinfo radeon" does not show "Whistler" as an available firmware. I have no idea what it's actually using!
Some other notes, in order of preference.
- I have working switchable graphics; DRI_PRIME=n works very well. (And I'd like to keep it that way)
- I'm using KDE Plasma DE. (And I'd like to keep it that way)
- I'm using Kubuntu 18.04 LTS. (And I'd like to keep it that way)
The reason I'm here is that I'm not really sure what to do about this? On the one hand, everything seems to be using the best available option. On the other hand, it's not working right.

Lubuntu 19.04 will not connect to Visible r2 phone
Tried connecting the R2 without a driver.
I could send a file from the desktop to the phones giant memory card, (256GB) but only one file @ a time.
It would not create directories or copy anything inside a directory.
I then installed the drover for Linux included with the phone.
After a ton of reboots, trying it every way possible...even trying linux file transfer program...no good.
Anyone encountered this?
It blows my mind Linux does not snap right to one another. Kind of insane.

[ubuntu] S.M.A.R.T. Data Conundrum. Opinions Please.
I have a 7 Ubuntu 18.04 LTS machines with the same specs including 4 - 1TB hard drives in arrays. A few of the drives kept dropping out, I suspected that the power connection to the drive was not good since I could not feel the drive spinning. I fiddled with the power connections and got the drives to run reliably. Those problems seem to have been bad patch cables. I also decided to monitor the situation and see if the drive was at fault. On two of the drives I had began getting indications that the drives were failing due "Spinup Retry Count". I even bought replacement drives, however before I could get around to replacing them the S.M.A.R.T. data returned to normal and the "Spinup Retry Count" is now at 0. I'm using Gnome-disks to read the S.M.A.R.T data.
I know the safe thing to do is replace the drives but it also seems to me that the drives are actually fine. It seem that the S.M.A.R.T. date is reset from time to time, which I wasn't aware of until now.
What's you Opinion?

[ubuntu] Bluetooth connect and reconnects constantly
Hello. I bought some new Bluetooth earbuds. Soundpeats Truengine 2. They connect via Bluetooth, work for a few seconds and then start pairing again. They connect and disconnect continuously. It is interesting because I have a pair of Soundpeats Truecapules that work flawlessly. I am also using 2 other Bluetooth speakers without a problem. Any ideas what might be going on here?

Dell WD19TB Dock - Failed to Authorize Device
I have a Dell XPS 13 7390 "Developer Edition" that came from Dell installed with 18.04.3 LTS. We ordered a WD19TB Thunderbolt dock to connect peripherals and I can't get it working right. When I first plugged in the dock, an external HDMI monitor connection worked correctly, but none of the USB 3 ports worked, nor did the gigabit ethernet. When I looked in devices -> Thunderbolt, I saw that the system had detected the dock, but that it was in a "pending" state:
![]()
I clicked on the dock name in that screen and this dialog popped up, asking me to "authorize and connect" to the dock:
![]()
I click the "authorize and connect" button, and after typing in my sudo password, I got another dialog stating "Failed to authorize device: kernel error."
![]()
After this, back on the devices->Thunderbolt screen, the dock shows with an error:
![]()
Dell support directed me to this forum for assistance. Are there any special drivers that I have to install? What do I have to do to get this WD19TB dock working?

Cannot use iGPU and stuck in software rendering
I recently built a new system using an ASrock Rack E3C246D4U motherboard and a Xeon E-2288g. The box has no GPU installed and my intention is to use the iGPU that comes with the CPU. I installed Ubuntu 19.10 (desktop version) via the IPMI and rebooted only to have the system freezes at a purple screen. Couple more reboots and the same result
When it is in this state, the directly connected keyboard and mouse are unresponsive as are the virtual ones via the IPMI interfacewell, sometimes the mouse will wiggle around but the keyboard might as well be unplugged. The only way that I have been able to get it to fully boot and bring up Gnome is to add nomodeset via the GRUB edit feature when booting and then permanently add it to the grub file once the system is up. (I also removed the quiet-splash flag from the grub file so that I could better see what was going on during boot.) Now it boots but I am stuck with a 640x480, 8-bt color, slow as dirt UI because the iGPU is being bypassed in favor of software rendering. Does anyone have ideas on how I can regain the use of the iGPU and avoid the freezing of the system?
Other things to note. Once I was able to get it up and running, I did do a sudo apt update/ apt upgrade AND set the default graphics in the BIOS to use the iGPU.
Also (I am a bit new to Linux) where can I find information on what gets disabled when nomodeset is applied and or find system logs of possible errors/conflicts occurring at boot?
Many thanks in advance for any and all ideas and support offered!

Problem setting up Canon printer
I'm setting up my laptop after converting to Ubuntu 19.10 from windows and having difficulty with the printer. I have a Canon Pixma 8520. Trying to set it up through CUPS and the printer is not responding. The printer and laptop are on a wireless network. i installed the driver from a Deb file because I couldn't find one for my printer from the list on the Ubuntu install.
In CUPS I set up the printer and driver, calling it Canonxx, It is set up with the ip address found in the terminal by pinging myprinter.
The other canonpixma i set up in CUPS with the IP address I found on the printer's screen.
When I searched for network printers in CUPS I did not see any, so I set both up manually using the IP addresses above.
After setting them up I checked in the terminal and got the following:
and
when I check the Canonxx printer in CUPS I get
CanonXX (Processing, Accepting Jobs, Not Shared)
Driver: Canon TR8500 series Ver.5.50 (color, 2-sided printing)
Connection: http://198.105.244.23
But I cant print anything. Nothing on the canonpixma and with the CanonXX, first I get a message that I am connected to the printer and then that the printer is not responding.
I'm just getting started in Linux so am probably missing a simple step. Can anyone point me in the direction of how to correctly set up my printer?

Cannot access flash-drive/usb-drive
My USB flash drive is no longer working after using it at one of this self-service-photo-print-machines. The software on that machine crashed when I was scrolling through my photos on my flash drive and just wanted to change the viewing order of the files. I was not able to read anything from the flash drive after that crash.
Inserting the drive on my Ubuntu 18.04.3 LTS and looking into the /var/log/syslog, I see the following (related) error messages:
The flash drive seems to be recognized, although the size is wrong, it has 128 GB.
After those messages, however, the Buffer I/O error appears:
The following part is repeated 8 times:
The final part is as follows:
I am worried about the unable to read partition table part, but that might be related to the Buffer I/O message.
I have no idea how to restore my flash drive, as # smartctl -a /dev/sdb results only in
Manually setting the type with # smartctl -d scsi -a /dev/sdb gives the following output (local time and serial number removed as they should not be important)
Again, wrong size.
Any suggestions how I could try to get access to my flash-drive are greatly appreciated!

Very annoying lag Linux Ubuntu 18.04.3 LTS with external display from Samsung
Hi all,
I'm new to this forum and wanted to solve this problem as much as I could no my own but it's starting to get reeeally annoying now.
So I have an HP Omen with an Intel® Core i7-8750H CPU @ 2.20GHz × 12 processor and GeForce GTX 1060/PCIe/SSE2 graphicscard.
I configured as a dual boot. Study on WIndows, developing on Linux. The problem is an enormous lag when working under Linux 18.04.3. It's almost not workable anymore.
Does this have something to with my current drivers or maybe in the NVIDIA X server settings?
The Samsung model is: S24F 352FHU
Hoping you guys got the answer :)
