Bug 17967 – trident framebuffer support broken in gentoo-sources 2.4.20 - any revision

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Michele Noberasco (RETIRED) 2003-03-21 20:08:21 UTC]

I compiled gentoo-sources 2.4.20 using the .config from gentoo-sources 2.4.19.
Trident framebuffer doesn't work properly: I'm stuck at a resolution of 640x480,
8bpp, whichever parameter I pass to the kernel at boot time.

Relevant output from dmesg:
tridentfb: Trident framebuffer 0.7.5 initializing
tridentfb: framebuffer size = 8192 Kb
tridentfb: PCI device 1023:8620 (Trident Microsystems) board found
tridentfb: 1024x768 flat panel found
Console: switching to colour frame buffer device 80x30
tridentfb: fb0: Trident frame buffer device 640x480-8bpp

On gentoo-sources 2.4.19 and ck-sources-2.4.20 tridentfb works well at 1024x768,
16bpp using this parameter:
video=trident:1024x768,bpp=16,accel,memsize=8192,fp,nativex=1024
or this one:
video=trident:1024x768-16@60 accel fp memsize=8192 nativex=1024 bpp=16


Reproducible: Always
Steps to Reproduce:
1.compile kernel with trident framebuffer support
2.boot it with the parameters above

Actual Results:  
Stuck at 640x480, 8bpp and an ugly flickering (on a LCD!)

Expected Results:  
A nice 1024x768 16bpp screen

My machine is a Toshiba Satellite 1800-400:
384MB ram, Trident Cyberblade Ai/1 video card that uses 8 MB of system memory

My CFLAGS:
CFLAGS="-march=i686 -O3 -pipe -fforce-addr"

My USE:
USE="acpi apache2 apm arts avi cdr crypt cups dga directfb dvd encode ethereal
fbcon -gnome gpm java jpeg kde ldap mmx mozilla mpeg oggvorbis pcmcia png pnp
quicktime samba sse ssl tiff truetype usb wmf X xmms xv"

could you please tridentfb on pfeifer-sources-2.4.20_pre9?

Thanks,

I tested it pfeifer-sources-2.4.20.1_pre10 and trident framebuffer works great!
