Dear All,
I operate a server (no keyboard, no mouse, integrated intel video i82G33/G31). When I switched from 8.04 LTS to 10.04 LTS the server stated to freeze after a few minutes of operation. Normal access to the command line is via SSH. On learning from the web about the intel driver/X problem I shut gdm down intending to finish the configuration of other services (this is a SAMBA and LAMP server). The server still froze after a few minutes or hours. I only observed one case of desktop freeze since I only ran one interactive graphic session.
I downgraded the kernel from (lucid-updates 2.6.32-22) to (lucid 2.6.32-21). The same kernel mentioned above (i386 generic-pae in my case). The sitation improved: the server stayed online for several hours, but never lasted a day. I reenabled KMS, and generally applied all the recipes listed in the Ubuntu.fr forum which do not degrade 3D performance. I installed more recent intel 2.9.1 drivers to no effect. With KMS the i915 driver stays loaded all the time and cannot be unloaded, but with gdm stopped and no interactive session it shouldn't have been exercized significantly.
The solution came from the installation of lucid's 2.6.31-rt kernel, which works for me, as it worked for Thomas (post #54).
Other symptoms are similar: no oops recoverable, no crash file, nothing relating to a serious kernel problem in any log file. I did not try to store log file remotely though. The freeze seems to be instantaneous, but it is not related directly to graphical session activity.
