Suse 10.2 Dell 2405 and getting 1920 x 1200 to display properly

The PIT · 08-06-2007, 03:03 PM

If I let Suse go and detect the settings I just get cannot display this mode.

Played around with the xorg.conf with no success.

I found this suggestion here

Section "Monitor"

EndSubSection
Device "Device[0]"

Monitor "Monitor[0]"
EndSection

which doesn't cause the error "cannot display this mode" but it still isn't displaying at 1920 x 1200. According to the Monitor is running at 1600 x 1200 and the screen looks horrid.

Changing it in yast makes no difference so what now???

SuSE has a nice utility for seting the display. It's called sax2. Give that a try. You can run it with or without X running. I had better experience with it when I did not have X running. You can boot into run level 1 to get SuSE to run in console mode, then log on as root, then start sax2.

The PIT · 08-06-2007, 03:35 PM

well I tried with init 3 after making sure x was killed off and just got back to square one.

Since then I've run xorgconfig which has given me a screen at 1600 x 1200 which I can put up with but I'd still like to get 1920 x 1200. I'll come back tomorrow with the new xorg.conf file it generated. I'm off to get some shut eye right now.

See if you can follow this method to set your resolution. It has to do with your Monitor selection and LCD should work for most flat panel users:

K-Menu/ YaST/ (Enter root Password)

Hardware/ Graphics Card and Monitor/

Display 1 Tab/ Monitor--> Change /-->LCD/ 1920X1200@75HZ

OK/ OK

Thank You,

If I do that I get cannot display this mode. Sort of annoys you really. Just booting Linux now.

Okay heres the xorg.conf created with xorgconfig. Just the monitor section. This gives me an readable 1600 x 1200

Given up for now. I'm running on an analogue cable by the way as my other pc is plugged in to the DVI connection.
I don't think I'm going to get this to work at the correct res.

The PIT · 08-16-2007, 08:00 AM

Well there were some updates to fix this issue but of course they didn't so I'm still stuck at 1600 x 1200.

Any other ideas???

Thank You,

Dells only run at 60hz at 1920 x 1200 hence the cannot display this mode message.

Still stuck at 1600 x 1200

Your 'Monitor' section has this line:

Quote:

VertRefresh 56.0-76.0

Xorg might be trying to give you its 'best' refresh rate, ie, 75Hz - which, as you point out, the Dell screen will not sync to. To restrict it to 60Hz, try telling it lies. Put this line in instead:

Quote:

VertRefresh 56.0-61.0

A long shot, but worth a try. I had to resort to this type of trick to force Xorg to 60Hz when my desktop LCD monitor kept complaining about the 'non-optimal' 75Hz refresh rate being fed to it, when the VertRefresh line was: 56.0-75.0.

I tried 50-60 and it still stuck at 1600x1200 but with very distorted fonts.
Anyway last night I spotted some more updates for sax2 which broke sax2 altogether. That won't even load now. Fantastic.

The PIT · 08-24-2007, 02:53 PM

Now this is funny.

Ran Sax2 from the command line and got 1900x1200 under root.
rebooted and got 1600x1200 logged off and it switched back to 1900x1200.

Sax2 is still broken in yast though. Another problem.

There are a few problems with your xorg.conf file. In the 'monitor' section, this line:

Quote:

# USER MANUAL FOR THE CORRECT NUMBERS.SubSection "Display"

should be two separate lines, like this:

Quote:

# USER MANUAL FOR THE CORRECT NUMBERS.
SubSection "Display"

In the 'graphics device' section, this line:

Quote:

# Clocks 25.2 28.3SubSection "Display"

should also be two separate lines, like this:

Quote:

# Clocks 25.2 28.3
SubSection "Display"

Does your xorg.conf file actually have those lines combined? Or was this just caused by the way you transferred the contents of the xorg.conf file to this thread? If it really looks like that, you should edit it to fix those errors.

The 'monitor' section makes no mention of display size. You could add this line:

Quote:

DisplaySize 518 324

As well, although the 'monitor' and 'graphics device' sections define a 1920x1200 mode at depth 24, this is missing from the 'screen' section. In the 'screen' section, try changing:

Quote:

Subsection "Display"
Depth 24
Modes "1600x1200" "1280x1024" "640x480"
ViewPort 0 0
EndSubsection

to:

Quote:

Subsection "Display"
Depth 24
Modes "1920x1200" "1600x1200" "1280x1024" "640x480"
ViewPort 0 0
EndSubsection

After you've finished editing the file, log out, press the Ctrl-Alt-Backspace key combination (this kills the Xserver and restarts a new one), log in to the new version of X, then see if you can select 1920x1200. Hope this helps.

Because I copied and pasted it. Anyway since doing it from the command prompt it's written a slightly different xorg.conf and this seems to work . So applying the rule if it ain't broke don't fix it I'm leaving well alone.
Interesting since I've done this the whole Linux is much quicker in response. Weird.
