<pre>Hi !
First I don't really know if my problem is posted at the right place, sorry for
that, but I don't really understand all the categories...
I got some wrong text rendering in console, and some missing graphical object
under X.
I've found some messages in logs such as :
Sep 18 15:39:44 pluton kernel: [ 176.941808] [drm] nouveau 0000:01:00.0:
PFIFO_CACHE_ERROR - Ch 3/4 Mthd 0x0000 Data 0x88000004
Sep 18 15:39:44 pluton kernel: [ 176.941840] [drm] nouveau 0000:01:00.0:
PGRAPH - ERROR nsource: ILLEGAL_MTHD nstatus: PROTECTION_FAULT
Sep 18 15:39:44 pluton kernel: [ 176.941854] [drm] nouveau 0000:01:00.0:
PGRAPH - ch 3 (0x00075000) subc 4 class 0x0000 mthd 0x0180 data 0x00007308
I've found that this bug is old but can't find a solution.
I've tried to install the Nvidia driver, but it freezes at boot, even I made a
/etc/X11/xorg.conf file (with nvidia-xconfig).
I'm running Debian Wheezy (up to date):
uname :
Linux pluton 3.2.0-4-rt-686-pae #1 SMP PREEMPT RT Debian 3.2.89-2 i686
GNU/Linux
Can you help me solve this ?
Please note that english is not my native language, so write as simple as you
can.
Thanks a lot.
Best regards
Philippe</pre>
