Hi
I am experiencing the following: Firefox, Chrome, LibreOffice freezes my
FreeBSD-CURRENT after a few seconds (the disk is used intensivey but nor
keyboard nor mouse is working, I can move the mouse pointer but nothing happens
when I click with any of the buttons), nothing is written on the screen. As the
mouse seems to not work I am not able to start any other application after
starting the above programs. before starting those programs xterm, clang, etc
is running correctly.
Ctrl-Alt-Del kills the xorg server, and the laptop returns to the character
based screen. I can start X again with startx, and it behaves in the same
manner.
A week ago when the above first happened then (as it was recommended in
pkg-message) recompiling xorg-server with the FIXDRM option corrected the
problem, but as FIXDRM is now removed I am not able to use those applications.
I tried to force the usage of dri3 as recommended, but did not help.
The system is a Lenovo T510 laptop, Intel I5-M520 CPU, integrated Intel
Graphics , FreeBSD-CURRENT #358833, ports installed from pkg repository.
best regards

Tárgy: users of drm-legacy-kmod or drm drivers from base
[ This is cross-posted across several mailing lists for maximum
visibility. Please respect reply-to and keep replies to x...@freebsd.org

In order to improve support for the new lkpi based graphics drivers
(drm-kmod) and to improve the graphics stack we have switched mesa to
prefer DRI3 over DRI2. This was done in r528071. For those using
drm-kmod, this should improve performance somewhat, and more importantly
alleviate the use of the FIXDRM option (now removed) in xorg-server.
However, for those of you using graphics/drm-legacy-kmod or the drm
drivers in base, this change can cause issues. If you are experiencing
problems when running OpenGL applications, you can force the use of the
DRI2 backend.
To force mesa to use DRI2, set the environment variable
LIBGL_DRI3_DISABLE to 1 before starting any OpenGL application. The
easiest way to accomplish this is by adding it to either your shell
startup file or ~/.xinitrc.
As an example, for users of [t]csh, put
setenv LIBGL_DRI3_DISABLE 1
in ~/.cshrc.
For users of bourne type shells (sh, bash, ksh, zsh, ...) instead put
export LIBGL_DRI3_DISABLE=1
in ~/.profile
If you are using these legacy drivers, I'm also very interested in
hearing what issues you are facing that prevents you from using the new
lkpi based drivers.
