Janez Janez, I seem to remember having a similar problem with a lab full of those machines some years ago. They were running an earlier version of Fedora. What we had to do was upgrade the BIOS. They are now running Fedora-11 with BIOS ver 2.6.2 Hope this helps, Tony ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you boot the system in runlevel 3 and then change the driver to i810 in the device section of /etc/X11/xorg.conf : Section Device Identifier Videocard0 Driver i810 EndSection Good luck, Edwin ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The bios update and the i810 driver and nothing worked. After the bios update the vesa driver seems a bit more stable, but still not 100%. And with the i810 driver it doesnt work at all. When X starts the screen starts to blink and does this forever (it didn't stop after 15 minutes, i didn't wait longer). When i looked at the Xorg log it says that the i810 driver is not the correct one for this chipset and that i should use the intel driver instead.

Janez ___ Could it be that Dell has different types of Graphics controllers in their Optiplexes? It did work in my model. I've been installing with 5.3 x86_64. The same redhat version though did not show any problems. Here's output of my lspci, maybe you can see some differences.
