Upgrade to Intrepid broke X (I830WaitLpRing timeout)

[noah]

I upgraded from Hardy to Intrepid Ibex some days ago and now X is broken.

After a cold boot X loads fine but short after logging in X locks up.
Keyboard is dead. SSH works fine though.
Trying to restart KDM or GDM results in X crashing over and over again.

I've also tried dpkg-reconfigure xorg-xserver to no avail.
Not even using the framebuffer works.

The hardware is an HP/Compaq D510 SFF with an integrated graphics controller.

I've searched Launchpad for similar bugs but most were related to Gutsy or pre-Hardy and appear to have been fixed.

There's a new xorg intel driver (2:2.4.1-1ubuntu6). Try it!

[Hong Yuan (hongyuan1306)]

I have exactly the same problem with Intrepid Alpla6, which is using the 2.4.1-1ubuntu6 version of the intel driver.

My motherbord is a Gigabyte EG43M-S2H with the G43 IGP.

Ubuntu can not start with the default session. It works with xfce4 though. But when the program is doing some more intensive graphics, like animation, window expanding e.g., the X server will often crash.

Some other users are also experiencing this with the G43 chipset. See: http://ubuntuforums.org/showthread.php?s=46351871546530d7c8625576d5d706ee&t=889323&page=2

This error is making the new G43 board almost unuseable for Ubuntu.

[Hong Yuan (hongyuan1306)]

Additional note: the bug remains the same with newest version of the driver xf86-video-intel-2.4.2.

A temporary workaround is to disable hardware acceleration through the xorg.conf file:

Section "Device"
        Identifier "Configured Video Device"
        Driver "intel"
        Option "NoAccel" "True"
EndSection

I am having a similar problem. After upgrading, xorg crashes during login. I get to the gdm login screen, but after entering my user name and password, it crashes. The error in /var/log messages is Xorg[6907]: segfault at 0 ip b7b00dc1 sp bf821af0 error 4 in libdri.so[b7afd000+8000] .

[Sabin Iacob (iacobs)]

in my case, X works fine for a while and then crashes when I start Mozilla Thunderbird; subsequent attempts by gdm to restart X fail and the screen is unreadable (looks like it sets a wrong refresh rate or smth... all static and lines - also on text console, when switching to a text console I catch a glimpse of the dialog box that tells me X keeps crashing (I think))

Sometimes a restart solves the issue and Thunderbird starts fine afterwards, sometimes it takes 3-4 restarts.
relevant lines from /var/log/messages:

Also attaching Xorg.0.log (the last crashed one... I have yet to find a way to keep it from restarting like crazy, other than running with startx, that is)
