Bug 15512

list of the hardware (output of lshw in the terminal))

Hi,

I was referred here by Bryce Harrington, from Launchpad.

There is a bug in the "intel" driver, only when running on a machine with the 
Intel 945 chip (Intel(r) 82945GM Chipset Family Graphics Chip).

I could only install Ubuntu 8.04 Hardy Heron Beta with the Alternate CD because of this bug. When I booted the laptop after the installation, a seemingly normal login screen appeared. However: when I typed in my login name, the letters were absurdly huge and didn't fit in the login screen input field. After filling out my password and pressing Enter, X wouldn't show: the screen became black and stayed black.

I applied this workaround: a switch to the "i810" driver, which doesn't have this problem. So I had to reboot into recovery mode and run "apt-get remove xserver-xorg-video-intel"
This way I uninstalled the "intel" driver, leaving only the "i810". Then I rebooted the laptop. Now Ubuntu 8.04 boots correctly into X.

This happens only with the Intel 945 chip. On another laptop with the Intel 915, there was no problem at all. Also there is no problem on a desktop computer with the Intel 946.

I have attached the output of lshw.

I hope you can fix this bad bug in the "intel" driver, before Ubuntu 8.04 ships in its final version. It's almost impossible now, to run Ubuntu 8.04 on a laptop with the Intel 945. I should add, that I encountered the same problem in PC-BSD 1.4.1, so it's not a distro-specific problem.

Greetz, Pjotr.

(II) Module i810: vendor="X.Org Foundation"
        compiled for 1.4.0, module version = 1.7.4

This is the old i810 driver.

Please double check the driver version.

Here is the Xorg.0.log from the -intel driver:

status = RESOLVED
resolution = FIXED

fixed in xserver a while ago, commit c747030a49dd289e873e2b686cd129d840e55468
(LPL prod id 0x2a00 added to quirk_detailed_use_maximum_size)

Cheers,

marking as fixed for real now, hopefully.

The poblem is still there, in the "intel" driver that is in the Release Candidate of Ubuntu 8.04, that was released yesterday (April 18th).

I have attached Xorg.0.log from the LiveCD-session.

You need to take that up with ubuntu then, not here.

The fix has been applied to Ubuntu's xserver git tree but is not yet released, since we are currently in pre-release freeze.
