Subject: hi-res fb console with 2.6.0-testX ?
Date: Sun, 7 Sep 2003 21:51:51 +0200 (CEST) [thread overview]
Message-ID: <10539.80.202.106.246.1062964311.squirrel@to.server.sensewave.com> (raw)
The kernel command lines which work with vesafb and matroxfb in 2.4 do not
work for me in 2.6.0-testX.
kernel (hd0,0)/bz-2.6.0-t4mm3 root=/dev/hdc2 video=matrox:vesa:0x11A
kernel (hd0,0)/bz-2.6.0-t4mm3 root=/dev/hdc2 vga=794
both result in something resembling a Vesa 101 mode under 2.6.0-test4-mm3.
(640x480, 60 Hz)
I'd expect 1280x1024 in 60 Hz, which is what I get with a 2.4 kernel.
Doing fbset "vesa11A" causes the monitor to lose the sync.
Current vc then reports :
mode "1280x1024-61"
# D: 109.890 MHz, H: 63.594 kHz, V: 61.089 Hz
geometry 1280 1024 1280 1024 16
timings 9100 288 32 14 1 128 2
accel true
rgba 5/11,6/5,5/0,0/0
endmode
which looks about right, but the neighbor vc reports:
mode "640x480-203"
# D: 109.890 MHz, H: 101.002 kHz, V: 203.223 Hz
geometry 640 480 1280 1024 16
timings 9100 288 32 14 1 128 2
accel true
rgba 5/11,6/5,5/0,0/0
endmode
which appears to be a little off the mark....
(Got this by typing 'fbset', 'alt-F2, 'fbset' while the monitor was blanked.
I got my /etc/fb.modes from here:

[+ a little binary crap here.....]
Is the fbconsole support in 2.6 somewhat broken, or am I missing something
obvious?
