ubuntu-drivers devices 20.04 shows nothing

[Ralf Mardorf]

If you google for "VGA compatible controller: Intel Corporation
Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics
Controller (rev 35)" you get a lot of hits, such as

"1. Create a new text file called /etc/X11/xorg.conf.d/20-intel.conf
with your favorite text editor containing the following text. Since
this file resides in the /etc folder and not your home directory, you
need root or sudo access to create or edit this file: Code:

Section "Device"
    Identifier  "card0"
    Driver  "intel"
    Option  "AccelMethod"  "uxa"
    EndSection

2. If the section for Intel card is already present, just add the
following line: Code:

 Option   "AccelMethod"   "uxa"

3. Save the file and reboot." -

It's probably not the solution, but perhaps a pointer into the right
direction.

It's quite possible that the nowadays unsupported "intel" driver
mentioned by this thread from 2016 is a problem, for your hardware,
too. AFAIK several major distros migrated to the "modesetting" driver,
but maybe the "modesetting" doesn't solve issues for your hardware.



"i have added two lines (options) in my 20-intel.conf file located in
this path : /usr/share/X11/xorg.conf.d/20-intel.conf and i didnt have
any gpu hang problem for 3 days the lines that i have added are :
Option “NoAccel” “True” Option “DRI” “False”" -

The best Linux support existed for Intel machines, the reason for me to
migrate to an Intel machine. And today a lot of Intel machines don't
work correctly anymore.

...requires to migrate to the "modesetting" driver to get rid of issues
and to introduce tons of other issues instead, if I want to use recent
mainline/stable kernels. However, I stay with 4.19 longterm kernels
instead and continue using the "intel" driver. Not to mention that even
working hardware video acceleration is more or less useless, due to
less software support to use it.


For good reasons almost all attempts to establish Linux desktop
computers by public authorities or for any professional purpose
miserably failed. I stay with Linux as a pastime.
