Some experiences with squeeze on a laptop. 0) The problems below are (at least for me) tricky to debug. I'm asking for hints on how to obtain more information about what goes on so that I can make a formal bug report.
1) I'm experiencing some bugs with X on a laptop, either at wakeup or suddenly in the middle of a seemingly normal session. It does not really lock, but it totally borks my screen by replacing tiles of the original screen content on other places of the screen area so it does look somewhat of a caleidoscope image. The replacing may continue for 5-10 seconds and the limits between different tiles are somewhat fuzzy though. Sometimes the computer becomes extremeley slow and the cursor moves now and then in short steps. On one occasion I think it actually did lock, i.e. I think that X did not accept any input, and then I had to shutdown by the power button. 2) In some instances I have been able to shutdown the computer by painstakingly slow X moves. When it reboots everything is normal. 3) On other occasions I have been able to switch to a virtual terminal where no image/text is shown. Nevertheless I have been able to log in blindly as root and request a reboot. 4) A couple of times the same stuff has happened at wakeup. Interestingly, after closing the lid, waiting a short while so that it goes to sleep again, and opening the lid, the computer made a normal wakeup! 5) Further, the problem of non-existant screen output on virtual consoles have occured at several other times. Apparently, the VTs do in fact function but it without text it is difficult to use them. 6) The problems occur on my Dell M2400 laptop on which I run Debian for amd64. I started out with lenny but several weeks ago I upgraded to squeeze in order to get later versions of some packages. I run nvidia stuff from sid. The problems were present both with nvidia version 185.18.36-2. and the current 194.42-3. I am using kde and the 2.6.31 kernel from sid from which uname -a reports: Linux laptop 2.6.31-1-amd64 #1 SMP Sat Oct 24 17:50:31 UTC 2009 x86_64 GNU/Linux but I have seen the problem with the squeeze kernel 2.6.30 as well. The M2400 has a nvidia graphics card of type FX370M card for which lspci reports: 01:00.0 VGA compatible controller: nVidia Corporation Device 06fb (rev a1) The nvidia packages installed are: i nvidia-glx - NVIDIA binary Xorg driver i nvidia-glx-ia32 - NVIDIA binary driver 32bit libs i nvidia-kernel-2.6.30-2-amd64 - NVIDIA binary kernel module for Linux 2.6.30-2-amd64 i nvidia-kernel-2.6.31-1-amd64 - NVIDIA binary kernel module for Linux 2.6.31-1-amd64 i A nvidia-kernel-common - NVIDIA binary kernel module common files i nvidia-kernel-source - NVIDIA binary kernel module source i nvidia-settings - Tool for configuring the NVIDIA graphics driver i nvidia-xconfig - The NVIDIA X Configuration Tool 7) With lenny there were not any of these problems. In order to get X working and sleep/hibernate I had to use a backported 2.6.30 or 31 kernel from backports, and the nvidia drivers from sid. This suggests that the problems I'm experiencing now are are related to the squeeze configuration.
