Bug Description

I nuked the xorg.conf file on my macbook as a test.

Starting up X, I'm in 1024x768 instead of 1280x800. Why? It is using i810 instead of intel.

I uninstall the i810 driver. Now X complains "can't find i810 driver".

Something somewhere is presumably mapping my PCI ID to the string "i810" instead of "intel". :(

Both drivers will do the device, but the "Intel" one (should be) better. The i810 driver is not supported upstream any more.

For now, edit the xorg.conf to use the "intel" driver. I do agree that the default driver being picked is wrong.

*nod*. it is no problem since normally i do run with xorg.conf. i was just testing something that should, in theory, work

thanks

the problem is in hw/xfree86/common/xf86AutoConfig.c from the xorg-server sources. When we drop the i810 driver from the archive and symlink i810_drv.so -> intel_drv.so (as done in the vanilla debian package) we should be set. I'm not sure if upstream should fix this anyway. Probably yes.

Timo, if we do that (And perhaps we should...), we should do it early in Hardy so that it gives us time to address any issues people have with the new Intel driver / configs.

Since the intel driver doesn't like old Xinerama configs, perhaps a better fix than the symlink is to not install xserver-xorg-video-i810 by default, and have some postinstall script (in xserver-xorg-video-intel?) fixup the xorg.conf to bend i810->intel, and remove incompatible config settings.)

This would allow people to install the i810 driver beside the intel one, and manually switch back (or decline to edit the config).
