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

[Ralf Mardorf]

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.

Ralf
