Graphics very slow following Hardy Heron Alpha 1 upgrade on Intel 945 chipset.

[dariusz]

Following an upgrade from Ubuntu 7.10 to 8.04 Alpha 1, the graphics of most applications (most noticeably in Firefox and Thunderbird) have become slower and less responsive.

My computer is a Dell Inspiron 640m, with an Intel 945 video chipset.

Running Ubuntu in recovery mode, re-configuring X, and restarting corrected the problem.

Thanks for taking the time to report this bug and helping to make Hardy better. It would be helpful if you could recreate the problem, and attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.

Hi there,

If I set the session to "Failsafe GNOME", the scrolling issues and general
performance of the graphics is slightly better than if I log into GNOME
otherwise .. but still worse than before the upgrade.

Attached are my configuration and log files. Please ignore the Synaptic
Touchpad stuff ... that's a separate device that got broken during the
update. :(

Attached are my configuration and log files as they are on my system right now. The Synaptics Touchpad doesn't work either, in case you're curious. :(

I tried using an older xorg.conf file from before the update, and it works well! In Gnome, things are noticably smoother and faster. Now the login screen is in a weird resolution (640x480?).

I'm attaching the .conf file for reference.
