screen resolution too low on externen monitor

switch007 · 02-17-2005, 03:08 PM

I have an intel i852 with an iiyama Vision Master 1403 attatched, and im stuck at 1024 on 85Hz, i want 1152x768 at 75, which ive selected under in system-config-display. It didnt detect the monitor, its on generic at the moment. I tried going under 'Hardware' and 'Configure' but under CRT it doesnt list 1152x768!

In preferences, resolution it only lists 1024, 800 and 600 and refresh only 85.

This is my xorg config:

Thanks

masand · 02-17-2005, 03:40 PM

have u set this according to ur monitor

HorizSync 30.0 - 70.0
VertRefresh 50.0 - 160.0

regards

Distribution and desktop environment?

switch007 · 02-18-2005, 12:21 AM

Sorry, FC3 and Gnome.

My monitor spec says 'Max Sync Rate (V x H) 160 Hz x 70 kHz' so does that correspond with the HorizSync (70) and VertRefresh (160)?

masand · 02-18-2005, 12:47 AM

thats the max
but i think u need to enter the range,

from low--->max

regards

switch007 · 02-18-2005, 12:54 AM

How do i find that out? Its not in any spec i can find

EDIT: Oh, i found it, and those values are correct, what else could it be?

masand · 02-18-2005, 01:08 AM

what are those values???
we want the range not the maximum value

switch007 · 02-18-2005, 01:43 AM

The ranges in the config are correct

Tuttle · 02-18-2005, 04:05 PM

ok, try:

Code:

gtf 1152 864 75

then paste the output into the "Monitor" section, change "1152x864_75.00" to "1152x864" and restart the X server (ctrl+alt+backspace).

Hi,
Did you manage to find the solution? I have the exact same problem and I have not been able to figure out the solution for a week. I have a dell E772c monitor with an intel 82845G chip. I have tried various permutations of options (BusID, VideoRam, HorizSync, VertRefresh, NoAccel,...) and tried installing the driver from Intel's site. But nothing has worked so far. I am still stuck at 1024x768. The other option that is working is 1280x960. But there is another problem. I have XP too installed and 1152x864 is the resolution that works best for me. Otherwise the font & icons are too big or small. But if I use a different resolution, I have to keep adjusting the monitor's manual settings to fit the screen properly.

My xorg.conf is included below:

Which kernel version are you using?
Also, what happens if you remove the "#" from in front of the modeline in your config?
Could you try putting it in the monitor section like this:

Code:

Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Dell E772c"
	DisplaySize  320	240
	HorizSync    30.0 - 70.0
	VertRefresh  50.0 - 160.0
	#UseModes    "Valid"
	Option	    "dpms"
	Modeline    "1152x864" 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync
EndSection

Hi,
It just started again in 1024x768 with the line you suggested. The error in the log file is "Not using mode "1152x864" (no mode of this name)". Same happens if I uncomment the UseModes line. I am using 2.6.10-1.766_FC3.stk16 (the stk16 because it is compiled with 16KB stack which my wireless driver needs). I had the same problem when I had 2.6.9-1.667. I upgraded everything in the hope that it might be some know bug now.

Well, I have come to the conclusion that either the i810(i830) driver doesn't have support for that resolution or xorg isn't happy to use it. Xorg does support that resolution, I know this 'cos I use it. Sorry if I am of no more help to you.

pashok1981 · 02-20-2005, 12:46 PM

Ok! But can you tell me if there adjusting the modeline options can make the screen size & shape used by linux at 1280x1024 match that of XP at 1152x864 at 65Hz? I mean XP draws a perfect rectangle and uses all of the monitor. But when I start X in linux, all the lines are curved (and so are the edges of the screen). This is the most annoying thing for me right now as I can not keep adjusting the monitor every time I switch between linux and windows. I tried the values from gtf, but that did not work.
