How to configure a -quirk option for suspending when the lid is closed?

[Adam Funk-4]

I did a clean installation of Ubuntu-MATE on a family member's laptop
yesterday, and then we ran into the 'GPU HANG' bug in recent versions
of the i910 video driver.  I fixed that by following the advice here:

<https://askubuntu.com/questions/1305989/applications-fail-to-launch-in-ubuntu-20-04-desktop/1307395#1307395>

<https://www.dell.com/support/kbdoc/en-uk/000123893/manual-nomodeset-kernel-boot-line-option-for-linux-booting?lang=en>

adding the nomodeset kernel option.  Now we've hit the bug described
here:

<https://dev1galaxy.org/viewtopic.php?id=1996>

so the second time the lid is closed (qto suspend), the system won't
wake up properly.  The solution there is to use the command

sudo pm-suspend --quirk-dpms-on

but that relies on running the command in a terminal from the pm-utils
package.  How can I configure Ubuntu-MATE to use that option to
suspend when the lid is closed?

Thanks!

Hi,

I'm on a PC with i915. I only cared about issues related to my Intel
GPU, however, it's known that intel driver support stopped several years
ago. It just worked without maintenance for a relative long time. IIRC
kernels <= 5.4 still work for most, if not all Intel GPUs, when using
the intel driver. 5.4 is a longterm kernel, however I'm in favour of
the 4.19 longterm kernel, avoiding all kernels >= 5. Some issues,
probably yours, too, might be related to something else.

IIUC regarding
https://packages.ubuntu.com/search?keywords=xserver-xorg-video-intel&searchon=names
the "intel" driver isn't dropped, while the "modestting" driver isn't
available for current Ubuntu releases,
https://packages.ubuntu.com/search?suite=default&section=all&arch=any&keywords=xserver-xorg-video-modesetting&searchon=names
.

I'll do test related to the intel issue with my Ventoy Xubuntu 20.04
soon, since my Ubuntu 16.04 is close to EOL. Until now I only made tests
using my Arch Linux install.

I didn't make good experiences when using the "modestting" driver, I
migrated back to the "intel" driver and use 4.19 kernels instead of
latest 5.x kernels.

FWIW first my Arch Linux and second my Ubuntu 16.04 xorg.conf [1]. You
only need the "Device" section to chose a driver, you don't need
anything else, just ensure that there's no "Device" section in
/etc/X11//etc/X11/xorg.conf.d/ overriding the xorg.conf's "Device"
section. Install the packages providing "intel" and "modestting", if
available at all ;) and test both drivers. Probably 5.4 kernels,
https://packages.ubuntu.com/focal/linux-generic , are still safe, but
maybe build and test a kernel 4.19, too.

I'm a little bit confused by "Ubuntu and Debian (and thus other
Debian-based distributions too) have abandoned the xf86-video-intel
X.Org driver for all recent generations of Intel graphics hardware and
instead makes use of the xf86-video-modesetting generic driver in its
place." -

Regarding the hangs I get with Firefox when using my Ventoy Xubuntu
20.04 the "modestting" driver is used, since I experience those hangs
when using this driver on Arch Linux and there are no hangs, when using
the "intel" driver on Arch Linux and Ubuntu 16.04.

Regards,
Ralf
