Bug Description

Using Gutsy, after updating to the last package, X11 has become very slow.

Hardware: Thinkpad Z60t. (Intel GPU)
Driver: Intel

This is a serious regression.

00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

 xserver-xorg-video-intel 2:2.1.1-0ubuntu9

By slower I mean the moving of the window has become slow as hell. I don't use compiz.

I guess this is a duplicate of Bug #155985. Could you please check if glxgears is very slow too?
Btw. could you recheck it with the Gutsy Live CD? Maybe it is only a configuration issue.

I don't have a gutsy live CD.

and it has worked fine with gutsy until a recent upgrade.

I did a sudo dpkg-reconfigure xserver-xorg prior to fill that bug.

glxgears just crash X. So it is not a duplicate of bug 155985

I did apt-get remove xserver-xgl and it now works.

Note: I never asked to use that. I noticed it was started.

Have you installed XGL? Intel driver doesn't need it for compiz because of AIGLX support?

if you re-read my last you'll see that I deinstalled it. it was installed, I don't know why. I don't use compiz as I said elsewhere.
In both case something was done and broke.

I meant if you installed XGL before.
This might be connected to Bug #152104 . Maybe on some circumstances XGL is installed on Gutsy upgrade but it would be unlikely. I guess you both installed packages which depends on Xgl.

Sorry, it is Bug #155034 not the one mentioned above.

Refiling as an XGL bug since issue went away after removing it. Perhaps this is related to or a dupe of 136650?

Also, a larger question is why xgl got configured on the user's system without their awareness. Perhaps something they installed pulled it in?

More than likely they installed it long ago and forgot about it, it has no reverse dependencies. They only notice when they upgrade to gutsy because then it gets enabled automatically if installed.

xserver-xgl has been deprecated upstream, and removed from Intrepid. Closing the bug as won't fix.
