Hello all, this is my first post.
I am not sure if my problem can be solved. The problem is in my screen color depth, I am not sure if it is 16bit or 24, but it is low, In other linux distros like Mint 12 colors are correct. After days of searching forums I reached the conclusion that Its from kernel version and my new hardware. I dont want to use current kernel because of overheating bug (my processor is sandy bridge). With Mint 12 (and not windows 7) temperature rise with minimum of processes running and here in #! my laptop is cool and silent.
So I have to wait for some how the kernel bug solve or there is a way to have this kernel (2.6.32-5) and have better color depth.
You can find the color depth used in /var/log/Xorg.0.log:
cat /var/log/Xorg.0.log| grep -iE 'depth|pci'
Ok, it says that its 24:
(--) PCI:*(0:0:2:0) 8086:0116:1025:0504 Intel Corporation Sandy Bridge Integrated Graphics Controller rev 9, Mem @ 0xb0000000/4194304, 0xa0000000/268435456, I/O @ 0x00002000/64
(II) Primary Device is: PCI 00@00:02:0
"Default Screen Section" for depth/fbbpp 24/32
(==) VESA(0): Depth 24, (--) framebuffer bpp 32
(==) Depth 24 pixmap format is 32 bpp
Is there any way to change it to 32?
By creating xorg.conf or an xorg.conf fragment that specifies the color dept you want?
This may not always be possible, depending on the used resolution and available graphics memory.
I know that my system is capable of this color depth,
Once I tryed to make Xorg.conf by Xorg :1 -configure but it gave me error:
Number of created screens does not match number of detected devices.
Is it the correct way to make Xorg.conf?
in /usr/share/X11/xorg.conf.d/ there are some files, can I specify the 32bit color depth there?
Creating a new file in /usr/share/X11/xorg.conf.d containing a complete "Screen section" should work.
See http://www.techbitnbyte.com/tips-on-ele … in-ubuntu/ for an example.
Seems I am wrong.
See 'man xorg.conf':
24 is the maximum value for color-depth.
