[SOLVED] problem with the intel driver

tramni1980 · 04-04-2012, 02:53 AM

Hello!
I am running Slackware64-13.37 with kernel-generic-2.6.38.4.
Here is some relevant hardware info:

Code:

00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

The problem is that in kde, when I click with the right mouse button on the desktop, I get a window that is blurred with black and the text is almost invisible. The same happens when I click on the panel. This problem is not present in xfce. The driver I am using is "intel". Here is what glxinfo says:

Code:

glxinfo 
name of display: :0
Unrecognized deviceID 126
X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Serial number of failed request:  21
  Current serial number in output stream:  24

Obviously something is wrong, but I have no idea what. Can I somehow circumvent the problem, sacrificing some eye candy, but staying with kde?
I can go without direct rendering and compositing for example. The Xorg.0.log is attached.

Any suggestions will be appreciated.

Try to not only install the newer kernel from /testing (as you seem already to have done), but also the newer Mesa/libdrm. If that doesn't help I would recommend to try a kernel from the 3.2 series, may be that helps.

TobiSGD,

Many thanks, upgrading mesa and libdrm did the trick!

For a better performance on Intel graphics you should also install libxtc_dxtn:

http://www.t2-project.org/packages/libtxc-dxtn.html

This enables S3TC support in Mesa, important for games and some effects in KDE.
