fbset not working with tridentfb on 2.6.x kernels

fbset not working with tridentfb on 2.6.x kernels

[Helge Deller]

Hi,

I've tried the tridentfb a few times with the last 2.6 kernel series (e.g. 2.6.6-rc1, 2.6.5, 2.6.4, 2.6.3) and with none of those kernels switching resolution with fbset worked. Everytime just screen was just scrambled with weired random graphics pixel stuff.

modprobe tridentfb on 2.6.6-rc1 gives:
tridentfb: Trident framebuffer 0.7.8-NEWAPI initializing
tridentfb: framebuffer size = 8192 Kb
tridentfb: 0000:01:00.0 board found
tridentfb: 1024x768 flat panel found
tridentfb: fb0: Trident frame buffer device 640x480-8bpp

My system is a IBM R30 laptop with the following lspci output:
01:00.0 VGA compatible controller: Trident Microsystems CyberBlade/i1 (rev 5d) (prog-if 00 [VGA])
        Subsystem: IBM ThinkPad T30
        Flags: bus master, 66Mhz, medium devsel, latency 32, IRQ 11
        Memory at 80800000 (32-bit, non-prefetchable)
        Memory at 80500000 (32-bit, non-prefetchable)
        Memory at 81000000 (32-bit, non-prefetchable)
        Capabilities: [80] AGP version 1.0
        Capabilities: [90] Power Management version 1

I'm willing to test any patches to get this think working correctly....

Helge

That is a problem in the general layer. It hasn't been fixed yet.
