Hi all,
Previously, I got the problem that my screen will become blank after the boot and I figured it out that if I use "fbdev" instead of "intel", I can see the screen.
I upgraded the kernel to 3.2.0-33-generic-pae recently and hope to see if I could use "intel" driver again.
I removed my xorg.conf and hope that it will use intel driver.
However, I found that my computer is now always using "fbdev".
If I specify "intel" in /etc/X11/xorg.conf, I will get a failsafe screen:
Code:
Section "Device"
Identifier "Card0"
Driver "intel"
EndSection
Any idea to resolve this problem? I am quite suffered by the brightness problem. I know that I can only do this by using intel driver.
For nvidia (bumblebee) things, I can get it work:
Code:
$ glxspheres
Polygons in scene: 62464
Visual ID of window: 0xfc
Context is Direct
OpenGL Renderer: Gallium 0.4 on llvmpipe (LLVM 0x301)
7.731623 frames/sec - 7.483778 Mpixels/sec
$ optirun glxspheres
Polygons in scene: 62464
Visual ID of window: 0x21
Context is Direct
OpenGL Renderer: GeForce GT 620M/PCIe/SSE2
107.486518 frames/sec - 104.040930 Mpixels/sec
Thank in advance.
P.S. I have tried to use those kernel argument, but the xserver seems to be fail to detect the intel chip.
P.S.2 I also tried to "apt-get purge xserver-xorg-video-intel" and install it again.
