Re: debian squeeze on acer aspire one 751h
I am following the advice on this bug  report to setup the GMA 500
with the ppa ubuntu drivers on squeeze.
See  for some comments, vesa driver setup, and further references.
In my setup, I had X running at 1366x768 with the vesa driver, using a
patched grub-pc to support the GMA500.
I have taken the following steps:
1. download git head from the reference in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=533450#50 and unpack
2. for each of the packages, go to the directory, run
dpkg-buildsource, check the required references, install them and run
dpkg-buildpackage again, and install the resulting deb package (if you
install the source package, then use apt-get build-dep on each package
to install its references). Some of the packages require a
--force-overwrite option, as detailed in
3. after all the packages are build, edit /etc/X11/xorg.conf as
outlined in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=533450#65
Then I have in /usr/lib/:
-rw-r--r-- 1 root root 33020 Sep 9 09:50 /usr/lib/libdrm.a
lrwxrwxrwx 1 root root 15 Sep 9 10:33 /usr/lib/libdrm.so -> libdrm.so.2.3.0
lrwxrwxrwx 1 root root 15 Sep 9 20:23 /usr/lib/libdrm.so.2 ->
-rw-r--r-- 1 root root 31992 Sep 9 09:50 /usr/lib/libdrm.so.2.3.0
-rw-r--r-- 1 root root 34580 Jul 21 10:32 /usr/lib/libdrm.so.2.4.0
Then I changed my xorg.conf from Driver "vesa" to Driver "psb" and
reloaded X. It fails with the following errors:
(EE) PSB(0): screnIndex is:0;fbPhys is:0x7f800000; fbsize is:0x007bf000
(EE) PSB(0): First SDVO output reported failure to sync or input is
Anyone seen this error, or maybe pointers/ideas to fix it?
I am running kernel 2.6.30.
On the bright side, the psb kernel module publishes the backlight
files under /sys/class, and that allows me to adjust LCD brightness.
It also gives a nice (and slow) 1366x768 console.
