rebuilding xorg-x11-drv-intel to fix graphics problem

[Holger Levsen]

hi,

so I think I'm experiencing https://bugs.freedesktop.org/show_bug.cgi?id=112296
when running Qubes 4.0 with a 4.19 kernel on a x230, that is, since the following
line appeared in Xorg.0.log:

==> /var/log/Xorg.0.log <==
[ 19271.994] (EE) intel(0): Failed to submit rendering commands (No such file or directory), disabling acceleration.

since then, graphics is very slow / sluggish, eg opening new terminals
is quite very slow, despite the system itself is fine and not loaded.
I even can still watch videos... but the system feels like it is
running with a load of 20 while in reality it's almost idle.

So I would like to give try the patch from the above referred bug, which is
https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=e628d22673dfa494230e6f79ceff7d178137c71a

So, what's running on dom0:

[user@dom0 ~]$ rpm -qa |grep xorg-x11-drv-intel
xorg-x11-drv-intel-2.99.917-32.20171025.fc25.x86_64

So I try to get the source like this:

[user@dom0 ~]$ sudo qubes-dom0-update --action=download xorg-x11-drv-intel
Using sys-firewall as UpdateVM to download updates for Dom0; this may take some time...
No such command: download. Please use /usr/bin/dnf --help
It could be a DNF plugin command, but loading of plugins is currently disabled.

hmmm. because:

[user@fedora-25 ~]$ dnf download --source xorg-x11-drv-intel
[...]
xorg-x11-drv-intel-2.99.917-26.20160929.fc25.src.rpm

So how/where can I download the source package for xorg-x11-drv-intel-2.99.917-32.20171025.fc25.x86_64
?

Also, I'm wondering if it's worth this excercise or whether we are really
close to Qubes 4.1 and thus I could try upgrading to that? But then I would
also really like to know how to rebuild patched rpms from dom0...
