GMA900 i915 laptop resolution

[Gilbert]

Tried 6.04 flight4 with unlucky results. Currently there is no way to get the correct resolution working, 1280x800. I have tried vesa and i810 in xorg.conf, 915resolution, along with grabbing the latest from http://dri.freedesktop.org/snapshots/ I have successfully gotten everything to work in 5.10 with this laptop including the resolution (using 855resolution) w/ 3D acceleration and suspend to disk and memory.

I have and Intel GMA900 (i915) and I have absolutely no problems with resolution (1280x800, Acer 1641 WLMi) BUT (AND I SAID BUT >_<), the 915resolution package of Ubuntu (and Debian Etch) seems to be buggy.
I use the 915resolution official sources on the creator website, and I do :
make clean
make
sudo make install
cd /etc/init.d
sudo gedit resolution (don't put 915, because of link problems which is surely the 915resolution Ubuntu paquet bug reason)
put these lines in the file :
#!/bin/bash
/usr/sbin/915resolution 5c 1280 800 # verify ! read 91reso doc
exit 0
then exit gedit
sudo chmod 777 resolution
cd /etc/rcS.d
sudo ln -s ../init/d/resolution S02resolution

And that works for me (breezy or dapper)

Tried the i915 from http://www.geocities.com/stomljen/ Same results.

Using 1280x768 only gives me a blank screen. It seems to respond to the ACPI event of shutting down when pressing the power button.

Here is the end of /var/log/Xorg.0.log when using 1280x768

"Using 1280x768 only gives me a blank screen."
Same here. Responds to ctrl-alt-del

I can easily use 1280x768 with ubuntu's 915resolution if I use vesa-driver.

Also using 1280x768 together with 1600x1200 Xinerama setup is buggy: it works but does not display cursor at all. The background image

Well, my card is not even recognized by xorg-setup, and also the device manager crashes... all worked in 5.10 not in clean install of 6.04

Thanks for the reports.

Please take a look at the debugging instructions here:

https://wiki.ubuntu.com/DebuggingXAutoconfiguration

Some of it still applies to Dapper, and may provide valuable information.

Thanks again

Any update on this? Were the logs/ouput useful?

[Jerome S. Gotangco (jsgotangco)]

Yes we seem to be getting very similar bug reports regarding i915 and widescreen displays at the moment: Bug #35409, Bug #35755 and some more...will check then confirm.
