I am not well-verse on udev rules, but i am looking at ways how i can emulate / simulate a hdd (kernel device name) to pretend as thou a disk via utilising loop device.
Currently loop device is able to create a block device and creates /dev/loop[0-9]* devices.
There is also option / command to use mknod to create a node in /dev/ emulating /dev/sd[a-z]*

However, doing so somehow doesnt show up is the command lsblk. lsblk still looks at the /dev/loop naming convention.

This is how i create the loop device and remove :

Create:
dd if=/dev/zero of=vdd.bin bs=1M count=50
mkfs.ext4 qa-vdd.bin
mknod /dev/sdx b 7 500
chown root:disk /dev/sdx
losetup /dev/sdx vdd.bin


To remove:
losetup -d /dev/sdx
rm /dev/sdx

But lsblk do not see this as /dev/sdx but sees this as loop500 (Ubuntu 16.04)


hence, i read udev rules, hoping that this is possible to be done via udev rules detecting loop device and assigning proper /dev/sd[a-z]* device name.

Is this possible ?

Or any suggestion.

Hi,
I installed ubuntu 17.10, but it didn't recognised my sound card. no sound from the speakers and
the sound output device appears to be an analog device.

Trying to get better screen resolutions for this machine. Currently I can only get 1280x800 on the internal eDP1 display, and 1024x768 on the external VGA display. Here are some outputs of some common tests which might help in diagnosing the problem...

I've been reading up a lot, and tried various things. As far as I can remember, the only thing I have in place that isn't standard is a new file, /etc/X11/xorg.conf which contains the lines...

Code:

---

Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "sna"
EndSection

---

Beyond that, nothing I've tried so far has had any effect, so I have undone any changes I made, reverting back to a fairly stock standard Lubuntu installation. Any suggestions on how to get this video card working properly, so that it supports higher resolutions?

Hey my laptop HDD is about 3 years old. Sometimes then i move the laptop, it freezes and i have to restart it. I have run a SMART analyes and it says: "Disk is okay, one failing attribute is failing".

I have dual boot with windows and wont to make a clean install soon, to try new linux distribution and get less windows.

I was wondering if my HDD needs to be replaced before i do that?

I have an canoscan lide 60 connected 2 an mint 18.2 operating system.
I installed xsane, xsanae-commons, xsane-doc and libsane.

The scanner is detected by xsane but when it is trying to scan it results in "Failed to start scanner: Document feeder jammed".
There is an dead link to an mini how2 on this page:
https://wiki.ubuntu.com/HardwareSupp...sScannersCanon
With the information there i could handle it myself, but without i hope you can help me.
I have the same problems like Alan F in this thread [ https://ubuntuforums.org/showthread.php?t=899605] except that my cable is working and tested.
Alan F stated that he did 3 things that helped him following the mini how2:
1. "sane-find-scanner command was OK"
>>>i guess he means Xsane is detecting the scanner. That works !!
2. "dll.conf modified as shown"
3. "45-libsane.rules did not exist but I created it and added the lines as shown"

If you could figure out what step 2 and 3 include, or could provide other solutions you would be very helpful.

With regards, Johann

Hi

I got a brand new install of Ubuntu on a 2013 desktop and was wondering if there would be any benefit to me attempting to get drivers installed for the GPU that was in it. The monitor is currently plugged into the Intel board but there is a Radeon card in the PC as well.

IF no benefit then I'll just forget it but I was hoping that I could get some benefit (Like scaling which I don't currently have and screen image seems to be clipped at the bottom) since the card was there already, if the drivers are stil supported of course.

I'm having trouble with pci passthough, I have one nVidia card, and one AMD card. I want to pass the AMD card to Qemu, but I need to blacklist the amdgpu module to do it. However, whenever I do, I'm greeted with no signal to the nVidia card.

Ubunutu 16.04 LTS

Why does blacklisting amdgpu affect the nVidia card?

Hi All,

I am currently using a thinkpad t70 with ubuntu 17.04, and I only had an old (10 years or so I guess) wifi adapter lying around to use: Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (from lspci)

I am not very satisfied with the performance after a few months of use. Frequently the network will disconnect with no way to re-enable besides a script I wrote to disable and re enable the driver itself. Also, the general performance when connected is fairly slow, and I almost never get full bars. I have verified, of course, that the stock antennas are connected properly.

Can anyone recommend a more modern laptop wifi card that is definitely fully supported by current linux drivers?

Thank you for reading.

Hi,
I have installed (hardware) a GV-N520D3-1GI (gigabyte) graphics card. When installing Nvidia Driver, the installation program can't locate hardware. I understand it could be a conflict with an open source Nouveau driver.

When looking at Ubuntu software centre I've found libdrm-nouveau2 is currently installed, but I'm unable to remove due to many dependencies. I can copy & paste in the list of dependencies for libdrm-nouveau2 if this is related to the graphics driver not working.

I desperately need to have this graphics card running to gain accelerated graphics. Can you please help.

I've installed budgie over my regular 17.10 on my lenovo R60. There is no problem with Ubuntu but budgie flickers a lot and with every mouse movement over windows control elements (sliders, click boxes etc) provokes massive refresh and sometimes shows a big horizontal lightning across the whole screen. All other Ubuntu flavors run perfectly. What's going on here?

Ubuntu on my computer will mount one SD card on a USB reader with no problem. If I want to read another, I have to either unplug the reader and move it to a different USB slot or reboot. I am unmounting before trying to change cards. The next card after that I can move it back to the original slot and it will work. This is true with multiple cards, multiple readers, multiple USB ports and multiple upgrades of Ubuntu--I'm currently on 17.10, but I've had this problem for several years and several OS updates. I've tried adding the line sm_ftl to my /etc/modules and rebooting, that's the best a Google search turned up and it didn't work for me. Not a huge problem but annoying-any ideas for troubleshooting?

Team,

Fresh install of 17.10.
Looking great - Lenovo Yoga 910 - i7-7500 Kaby Lake -
My screen starts to flicker - screen is going insane.
I remember that I have to put nomodeset in my grub config.

My brightness WORKED before I put nomodeset in my grub config.
Now, the flickering is gone; but cannot change the brightness.
Any insight?

Here's my config:

I did a new install on this machine last night and have alway found it hard to get the sound happening in Linux. I have a speaker system plugged into the onboard sound and doesn't seem to matter what i select in sound settings/volume control i am getting nowhere. Seems a lot is greyed out like the speaker icon in the tray next to the date and sometimes when i am adjusting settings the speaker icon goes red therefore i guess showing me it is mute? I am sure the speaker system is on and plugged in. I always know as there is a sound it makes through the speakers. I think last time i did a fresh install on another machine a couple of years ago someone sent me a tutorial maybe but googling has not brought anbything reflecting this version of linux or anything close to it. I do understand ubuntustudio has all sorts of fancy sound things that i have found it impossible to master. I stick to stuff i can work with like audacity and cinelerra that doesnt rely on that

I have Lenovo Ideapad 320 15abr with an AMD A12-9720P RADEON 7 cpu. I dual booted the pc with Ubuntu 16.04 LTS. When I'm using Ubuntu the mouse and touchpad stop working. But if I use Windows 10 the touchpad and mouse works. Please walk me through the process of fixing this problem. :confused:

I'm not the op (who has disappeared) but I'm having the same problem.
I'm on an acer es1 something something.
I haven't updated my ubuntu for a while (I'll try it in a minute...).
I went into settings, mouse and touchpad, made it right-button as primary, and it hasn't changed anything.
I thought it had but nope.
If I click the right button I get the options menu and the left button is select.
I closed it, opened it again and it still *says* right button is primary, but that's not what it's doing.
And my touchpad isn't doing "tap.to select" - it's basically just a glorified scrollpad.

Ubuntu 16.04, latest hplip
I have tried for over a year to get my HP Deskjet 2540 to work wirelessly. I have read all post which purport to explain how to do it - all say that their method is foolproof but, although the printer works OK on USB cable I fail to get it to operate on wifi.
Can anyone point me to a DEFINITIVE set of instructions?

Why does the above printer drop its Enabled status and fail to operate? I know it is simple to correct this but it means opening System Settings, Printers and the HPDeskjet Properties , Policies and click the box next to Enabled. Is there a way to make it stay enabled without all that palaver?

Following a recent upgrade of Kubuntu from 17.04 to 17.10 my Hewlett Packard PSC-1317 All-in-one printer/scanner/copier is now a Some-in-one printer/copier: I can no longer scan. I have had a similar problem with at least one previous upgrade and have somehow managed to resolve it with advice from existing forum threads etc, although I cannot of course now remember how . This despite the fact that this printer is not on the list of sane supported devices here.


Attempting to scan from the HP Device Manager yields error message:

Code:

---

Failed to open device ‘hpaio:/usb/psc_1310_series?serial=UA4CICB26QT5’: Operation not supported.

---

Note that the device-uri per HP Device Manager console > View Printer and Device Information is slightly different

Code:

---

hp:/usb/psc_1310_series?serial=UA4CICB26QT5

---

. I checked file /etc/sane.d/dll.conf and `hpaio` - the last entry - is not commented out. The serial *does* match the sticker on the machine (although the last two characters are missing, for some reason).


Attempting to run any scanning utility, eg Skanlite or Xsane, simply results in a message that no devices are found or available, however, running sudo sane-find-scanner from console gives

Code:

---

found USB scanner (vendor=0x03f0 [hp], product=0x3f11 [psc 1310 series ]) at libusb:003:005 [usb coordinates vary].

---

I have hplip-3.17.10 installed, I have installed both automatically and with the manual process adapted from the somewhat out-of-date advice from HP here.


Adapting advice from here according to files and directories I actually have/can find, and the instructions within them, I have created two new files:


1. File /etc/udev/rules.d/hp-psc1317.rules (to augment /lib/udev/rules.d/60-libsane1.rules):

Code:

---

SUBSYSTEM!="usb_device", ACTION!="add", GOTO="psc1317_rules_end"
    \#Hewlett-Packard All-in-one PSC1317
    SYSFS{idVendor}=="03F0", SYSFS{idProduct}=="3F11", SYMLINK+="HP-PSC1317", MODE="0664", OWNER="root", GROUP="scanner"
    LABEL="psc1317_rules_end"

---

2. File /etc/udev/hwdb.d/psc1317.hwdb (to augment /lib/udev/hwdb.d/20-sane.hwdb):

Code:

---

usb:v03F0p3F11*
      libsane_matched=yes

---

Even after dis-/reconnecting the USB printer cable and even rebooting, no dice. Note that the file (pseudofile?) /dev/bus/usb/003/005 was already in place, I guess because the printer function is already good - I’m not really clear whether the scanner and printer, for all that they are the same physical device, should have the same USB coordinates?


That’s everything I can think of that’s relevant. Glad for any advice.
