Updated and Optimized Ubuntu Free Graphics Drivers

[carestad]

I have a test build of mesa for 12.10 here:
https://launchpad.net/~oibaf/+archive/test/

Untested (I am still on 12.04). Please test, if confirmed working I'll move it to main PPA.

I get a lot of these messages in my ~/.xsession-errors:

Mesa: User error: GL_INVALID_OPERATION in glDrawBuffer(buffer=0x405)

Like 5 per second.

This is probably some application not properly using OpenGL.

mesa 12.10 packages are now in the main PPA.

Hi Guys.
When I run glxgears in 12.04 I get...
EE r600_asm.c:122 r600_bytecode_get_num_operands - Need instruction operand number for 0xc.
EE r600_asm.c:122 r600_bytecode_get_num_operands - Need instruction operand number for 0x28.

Do you need more info?
Cheers.

Hi,

the last version of your intel PPA really boost the performances but give me this error in glxinfo

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: 22
Current serial number in output stream: 25

Thus some app do not works (ie. Google-Earth Glxgears)

My video card is:
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

My box:
Xubuntu 12.04 i386 NON-PAE
Tried with both with official kernel 3.2.0-33-generic and kernel compiled by me 3.6.3-vanilla

I found a workaround to Badalloc issue on 3d accell; I put inside .bashrc file this string:

export LIBGL_ALWAYS_SOFTWARE=1

Save and reboot

Now everything "seems" to work correctly

Hi again,
found a workaround; putting this value:

export LIBGL_ALWAYS_SOFTWARE=1

on .bashrc file, saving and reboot, seems that fix the issue.

You are right, there was a package left over after purging xorg-edgers, I had to downgrade it manually and all is fine now.

Yu may want to try the packages I just uploaded, if it still doesn't work you should file a bug with mesa as reported in the first post.
