cannot go from 1024x768 to 1280x800... any Help ?

neoAThome · 01-20-2005, 11:29 PM

while installation also i was trying to get the resolution of 1280x800,

but my Mandrake 10.1 didnt take anything more than 1024x768.

So even now when i try to change that using the 'config. yur comp' module, it screen just goes black, i can see the mouse but then after a few secs the mouse also freezes.

any options ??

I assume that you have a wide-screen laptop.
Try googling for "1280x800" modeline

Some possible XF86config modelines:

Code:

# 1280x800 @ 75.00 Hz (GTF) hsync: 62.62 kHz; pclk: 107.21 MHz
Identifier "16:10"
ModeLine "1280x800" 107.2 1280 1360 1496 1712 800 801 804 835
# 1280x800 @ 85.00 Hz (GTF) hsync: 71.40 kHz; pclk: 123.38 MHz
ModeLine "1280x800" 123.4 1280 1368 1504 1728 800 801 804 840
# 1280x800 @ 100.00 Hz (GTF) hsync: 84.80 kHz; pclk: 147.89 MHz
ModeLine "1280x800" 147.9 1280 1376 1512 1744 800 801 804 848

Sample from a dell .pkg file:

Code:

Section "Monitor"
	HorizSync    31.5 - 94
	VertRefresh  50 - 90	
        ModeLine "1280x800" 83.5 1280 1344 1480 1680 800 801 804 828
        # 1280x800 @ 75.00 Hz (GTF) hsync: 62.62 kHz; pclk: 107.21 MHz
        Modeline "1280x800"  107.21  1280 1360 1496 1712  800 801 804 835
        # 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
        # 1280x800 @ 85.00 Hz (GTF) hsync: 71.40 kHz; pclk: 123.38 MHz
        Modeline "1280x800"  123.38  1280 1368 1504 1728  800 801 804 840

Check your monitor in the monitor section of XF86Config. Are HorizSync and [/i]VertRefresh[/i] set according to specs of your monitor? This could explain the black screen but not the mouse problem.
Anything in the Xorg logfiles in /var/log ?
