Xorg.0.log from Gutsy (working)

Forwarding this bug from a Ubuntu reporter, Matthias Müller-Reineke:

[Problem]
System with i815 graphics fails to properly detect the monitor and thus provides only 800x600 resolution.  

This worked on the -intel driver back with xserver 1.3 and -intel 2.1.1 (Gutsy) providing 1280x1024, but regressed in Hardy and has been tested through Ubuntu Karmic Alpha-2.

[Original Report]
With upgrade to hardy the highest possible resolution reduced to 800x600.
In gutsy and dapper the highest resolution was 1280x1024@60 Hz on the same hardware.
The system was upgraded from dapper to hardy.
Chipset i815 (from Xorg.0.log)
Similar bug: #162136

in my GUTSY!-installation (for hardy with bug after reboot):

the xorg.conf in karmic doesn't have that, so it uses the default sync
ranges, and the 1280x1024 modes get rejected.  Given that DDC fails, I'm
not sure there's much more the driver can do here.

Comment 3 Robert Pogson 2009-11-02 06:04:53 UTC

I encountered this behaviour in the released version of Karmic Koala, Ubuntu 9.10. I installed in a VirtualBox VM and no monitor could be seen. The Vesa driver defaults limited resolution to 800x600. I had to supply an xorg.conf with sweep frequencies, not a good feature of a popular distro recommended for newbies. Can the default sweep frequencies be raised to include the more often used 1024x768? w3schools reports that only 3% of humanity use 800x600 while most use higher than 1024x768.

This issue is affecting a hardware component which is not being actively worked on anymore.

Moving the assignee to the dri-devel list as contact, to give this issue a better coverage.

No one is in a position to fix these bugs and with the removal of xaa it matters not. When an intrepid hw/sw archaeologist turns up, he will have plenty of fun on his hands rebuilding from scratch...
