Running Slackware Linux on Thinkpad T61
FrameBuffer Configuration in Slackware Linux for ThinkPad T61
Make sure that framebuffer is enabled in kernel.
For 2.6.x kernel tree enable the following options:
General setup --->
[*] Prompt for development and/or incomplete code/drivers
Processor type and features --->
[*] MTRR (Memory Type Range Register) support
Device Drivers --->
Block devices --->
<*> Loopback device support
<*> RAM disk support
(4096) Default RAM disk size
[*] Initial RAM disk (initrd) support
Graphics support --->
[*] Support for frame buffer devices
[*] VESA VGA graphics support
Console display driver support --->
[*] Video mode selection support
<*> Framebuffer Console support
Bootsplash configuration --->
[*] Bootup splash screen
Then configure the bootloader.
For lilo, add these lines:
vga=872
append="video=vesa:ywrap,mtrr:3"
For grub, append these to kernel:
video=vesa:ywrap,mtrr:3 vga=872
Important note:
The vga=872 dosen't give me the 1680×1050 mode in the console. This value is the best one for me after tried many mode numbers.
AFAIK, vesafb doesn't support 1680×1050 mode currently, neither does intelfb.
For more information about VESA, check http://en.wikipedia.org/wiki/VESA_BIOS, or Google.
There's a project named vesa-tng, by which, someone said, can manage this mode and other ones. But I haven't tried.
