PINE64

Hi there,

After I've updated my system, I've got the trouble: when I use Fn + some functional key, X.org crashes.




And some error with Panfrost:




It looks like a Debian issue, but maybe we can find a way to make Fn works.

I am also experiencing a lot of Xorg crashes since my last apt upgrade on 24/01/2020. Looking at the apt history, there was a bunch of packages related to the video drivers in this update:

[...] libegl1:arm64 (1.1.0-1+b1, 1.3.0-7), libegl-mesa0:arm64 (19.2.6-1, 19.3.2-1), libgl1:arm64 (1.1.0-1+b1, 1.3.0-7), libglapi-mesa:arm64 (19.2.6-1, 19.3.2-1),  libgles2:arm64 (1.1.0-1+b1, 1.3.0-7), libgbm1:arm64 (19.2.6-1, 19.3.2-1), vainfo:arm64 (2.5.0+ds1-1, 2.6.0+ds1-1), libglx0:arm64 (1.1.0-1+b1, 1.3.0-7), libgl1-mesa-dri:arm64 (19.2.6-1, 19.3.2-1), mesa-vdpau-drivers:arm64 (19.2.6-1, 19.3.2-1), mesa-vulkan-drivers:arm64 (19.2.6-1, 19.3.2-1), mesa-va-drivers:arm64 (19.2.6-1, 19.3.2-1), libglx-mesa0:arm64 (19.2.6-1, 19.3.2-1), libglvnd0:arm64 (1.1.0-1+b1, 1.3.0-7) [...]

I am using the i3 window manager and I can reproduce easily the crash: opening a file dialog in firefox (Open/Save), launching some GTK3/Gnome applications (evince, gedit...).

The Xorg log is not very helpful with only the following entries:



This is very annoying as I cannot use some applications anymore. I have not been able to find the root cause of the crash yet...

I have managed to find the bug is caused by the newly uploaded version libgl1-mesa-dri package (19.3.2-1), and more specifically to the code in rockchip_dri.so.
I have filled a bug in Debian bugtracker with a full backtrace of xorg crash: https://bugs.debian.org/cgi-bin/bugrepor...bug=949980
This bug is very annoying and I am surprised nobody is complaining...

The 5.5 kernel has got a fix which helps a number of applications, mainly GTK ones.

There are also a pile of fixes and improvements for Mesa which are not in 19.3, so you'll want to install a recent Mesa git.

i recommend using mesa-git instead of distro mesa. see here for details:

I've seen this too. Thanks for tracking down a stack trace!

My deb uninstaller at https://sourceforge.net/projects/debuninstall/ can probably take out that set of debs.  Not sure of an easy way of putting the old versions back.  It works by caliing dpkg -r and detecting whether that returned an error or not.  It keeps working through the set of files as long as each pass removes at least one.

you can either downgrade the packages with apt, or use mesa git (permanently or temporarily), or install a few day old git packages from experimental. so a lot of solutions.

I'm seeing that error with libgl1-mesa-dri 19.3.3-1 which was part of my install from the debootstrap yesterday.  I googled ""unw_get_proc_info" failed" and found this post.  This is testing after all, I'm not hugely surprised.  I just wonder if this deb is really the problem since it happens with 2 slightly different versions.

My crash happens starting X, I can see parts of my LXDE desktop then it crashes.  Right after the gpio-keys like the xorg log you posted on Debian bugs.  I was wondering if it was OsLookupColor and thinking about the color depth being apparently 24 instead of 32.


Have you managed to work around the error?  I had this Bullseye installed and working once too, but I screwed it up so I've been trying several times to reinstall.

One sort of odd failure mode I saw a few times including this one was a blinking underline text cursor for part of a second, then a mouse cursor in the middle of the screen, then back to text, over and over for 15 minutes or  more.  A couple times I gave up at that, this time I flipped to another virtual terminal, logged in, set multiuser mode as the default.  But it comes from X not being able to start I think, for a week or so.  My first installation worked normally, that was January 15.  So sometime in that range of a month something broke.

I downloaded the arm64 deb from https://packages.debian.org/unstable/libgl1-mesa-dri and installed it but it was the same version (19.3.3-1) I already had so it made no difference.  I wish I had kept my old debs.  So I need to find debs in Bullseye updated in the last 30 days, intersected with debs I have.  Then try the deb it replaced.  This file is also in Buster as libgl1-mesa-dri_18.3.6-2+deb10u1_arm64.deb but it has different dependencies, I just tried it.  I think this file isn't the culprit, it's a different one.

I tried the real experimental from https://packages.debian.org/experimental...i/download but that runs into first wanting libgcc-s1, and that gets into wanting GCC 10, which probably wants a bunch more stuff.

By the stacktrace posted in the Debian bug report it dies in midgard_compile_shader_nir but I'm not doing anything with OpenGL at all.  LXDE does use a bit of GTK (2 I think) but other than that I'm doing nothing with Gnome.

I presume this goes away if you add modprobe.blacklist=panfrost to the kernel command line (albeit at the cost of graphics performance)?
