compiz problem [Solved]

[DanAlucard]

after doing a "kernel-switcher switch linux-sabayon-3.0-r4" [reboot] and "equo upgrade" [reboot] on my Acer AOD250 netbook, my compiz fusion doesn't work.

I use fusion-icon, so i can switch to Kwin, but trying to run compiz in a terminal (as normal user):

Code: Select all

alucard@DanAlucard ~ $ compiz --replace
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0

it seems to be a glx problem, bcs now i haven't any hardware acceleration. (from now on all is on a root term)

Code: Select all

DanAlucard alucard # lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

DanAlucard alucard # glxinfo
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig

DanAlucard alucard # grep EE /var/log/Xorg.0.log

Ignore the touchpad problems, it works fine.

i have never touched any X.org config file.
also, i have a problem that changes my hostname to dhcppc3 everytime i start KDE. writing "sudo hostname DanAlucard" solves the problem. nvm if there is any connection. My /etc/hosts file have the right hostname.

Any ideas on how to solve this?

now, the problem is solved. Just update mesa from entropy.
you can use:

equo update && equo install mesa && equo deptest

that will update the entropy's database, install/update mesa and test if some dependencies are not met on the system.


@micia: thanks for helping me solving this issue the hard way

Hi,

Can you post the output from:

Code: Select all

eselect opengl list
equo query installed xf86-video-intel
equo query installed mesa


[DanAlucard]

@micia: thanks for the fast reply. There are the results you asked

Code: Select all

You are welcome

This looks fine, what about this command?

Code: Select all

eselect mesa list


You could try the Gallium version of the i915 drivers, this way:
(as root)

Code: Select all

eselect mesa set 64bit i915 gallium


(I am assuming you have a 64bit system)

[DanAlucard]

i've tried to switch to the mesa gallium driver, but nothing happens

i have a 32 bit netbook, so i omitted the "64bit" part

Code: Select all

DanAlucard alucard # eselect mesa list
i915 (Intel 915, 945)
  [1]   classic *
  [2]   gallium
i965 (Intel 965, G/Q3x, G/Q4x)
  [1]   classic *
  [2]   gallium
r300 (Radeon R300-R500)
  [1]   classic *
  [2]   gallium
r600 (Radeon R600-R700, Evergreen, Northern Islands)
  [1]   classic *
  [2]   gallium
sw (Software renderer)
  [1]   classic
  [2]   gallium *

DanAlucard alucard # eselect mesa set i915 gallium
Switching i915 to gallium

DanAlucard alucard # eselect mesa list

you can try to reboot and see if that makes a difference with glxinfo, if X Server does not come up (this should not happen, but knowing how to face it never hurts):

1) login as root

2) run:

Code: Select all

eselect mesa set i915 classic


3) run:

Code: Select all

reboot


this will revert the change you made and reboot the machine.

[DanAlucard]

i really appreciate your help, but rebooting was useless

still can't use anything that requires 3D composition (even Kwin effects)

[micia]

I have 2 ideas, they both involve using portage...

First of all, update the portage list using:
(as root)

Code: Select all

emerge --sync && layman -S


1) you could try to update mesa:
(as root)

Code: Select all

USE="pic" emerge -1av mesa


reboot and see if it helps.

if it doesn't:

2) the problem is that it can't find a symbol in a shared library, as you can see in:

Code: Select all

(EE) AIGLX error: dlopen of /usr/lib/dri/i915_dri.so failed (/usr/lib/dri/i915_dri.so: undefined symbol: _glapi_tls_Context)


You could try to disable the:
shared-glapi
USE flag and see if it works, you can do it running:
(as root)

Code: Select all

USE="-shared-glapi pic" emerge -1av mesa


reboot, and check if glxinfo is happy.

Remember to sync entropy and portage, by running:
(as root)

Code: Select all

equo rescue spmsync


after using emerge.

Edit: to be safer, enable the pic USE flag explicitly.

[DanAlucard]

installing mesa from portage with defult USE flags did the trick

it took a lot of time, but it worked. Thanks a lot micia

[micia]

glad to hear that

Be careful updating the packages with entropy now, since it could suggest you to install the version from entropy.
You should be careful to not install the entropy version unless it is a version corresponding to the one in portage, or more recent.
You can prevent downgrades from entropy to replace portage packages enabling the:
ignore-spm-downgrades
feature in your:
/etc/entropy/client.conf

Code: Select all

ignore-spm-downgrades = enable


(you have to be root to edit that file)

Out of curiosity, you didn't even enable the pic USE flag?
