Sunwatcher Posted December 23, 2008 Report Share Posted December 23, 2008 I have just installed Linux Mint 6 on one of my computers, but I cannot get the optimum resolution on my monitor. The monitor is an (older) NEC MultiSync LCD 2010X. It measures 20" and the optimum resolution is 1280x1024. Currently, is displays at 1024x728. I have an nvidia 6200 video card which Mint configured nicely. I have compiz working, and everything looks great -- except the resolution! Here is the content of xorg.conf: # xorg.conf (X.Org X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database. # # Edit this file with caution, and see the xorg.conf manual page. # (Type "man xorg.conf" at the shell prompt.) # # This file is automatically updated on xserver-xorg package upgrades *only* # if it has not been modified since the last upgrade of the xserver-xorg # package. # # Note that some configuration settings that could be done previously # in this file, now are automatically configured by the server and settings # here are ignored. # # If you have edited this file but would like it to be automatically updated # again, run the following command: # sudo dpkg-reconfigure -phigh xserver-xorg Section "Device" Identifier "Configured Video Device" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection Can anyone help?

Sunwatcher Posted December 23, 2008 Author Report Share Posted December 23, 2008 What is the output of this command in a terminal window ? xrandr -q Yves. xrandr -q gives: $ xrandr -q Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 50.0* 800x600 51.0 52.0 53.0 680x384 54.0 55.0 640x480 56.0 576x432 57.0 512x384 58.0 400x300 59.0 60.0 61.0 320x240 62.0 Quote Link to comment Share on other sites More sharing options...
theYinYeti Posted December 23, 2008 Report Share Posted December 23, 2008 Oh! That's not a good sign. You'll probably have to play with modelines to get to anything higher than 1024x768. I have no knowledge in this area though. Good luck. Maybe gtf can help you. Yves. Quote Link to comment Share on other sites More sharing options...

I have no knowledge in this area though. Good luck. Maybe gtf can help you. Yves. Sounds bad. Yves, if you have a moment, could you explain what exactly is not a good sign? I'm still trying to learn more about how my machines and linux work. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted December 23, 2008 Report Share Posted December 23, 2008 Normally when I've seen this sort of thing, the wrong monitor was chosen that didn't support higher than 1024x768, for example. I don't know if Linux Mint is using the new xorg or not, because now in Ubuntu 8.10 I don't see options so far for configuring the monitor as it tends to all auto-detect now in the new version of xorg. Check the monitor you have configured, if you have it configure correctly, but the resolution won't let you go higher than this, then ensure that you use Generic CRT or Generic LCD and choose the one that supports your maximum resolution. Then you should be fine. Of course, don't try to use too high a mode, else you could cause problems to your monitor. Only use what you know it supports.

daniewicz Posted December 23, 2008 Report Share Posted December 23, 2008 Good advice Ian. I was going to suggest that Sunwatcher edit his xorg.cong file and add an appropriate modeline, but I like your suggestion better. Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted December 23, 2008 Report Share Posted December 23, 2008 On just checking, it does have the latest xorg (since it's based on Ubuntu 8.10), so it will be auto-detecting everything like I have it. My xorg.conf looks like this: Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 2704 1050 EndSubSection EndSection Section "InputDevice" Identifier "Generic Keyboard" Driver "kbd" Option "XkbRules" "xorg" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" EndSection Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "HorizEdgeScroll" "0" EndSection Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Synaptics Touchpad" EndSection Section "Device" Identifier "Configured Video Device" EndSection output of xrandr -q command: root@esprit:/home/ian# xrandr -q Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 2704 x 1050 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1680x1050 60.6*+ 1600x1024 60.2 1400x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 1152x864 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 TV disconnected (normal left inverted right x axis y axis) now, I know that my monitor maximum on my laptop is 1680x1050, and yet my monitor config looks like this: Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 2704 1050 EndSubSection EndSection xrandr reported a max of 2704x1050 as shown by the screen section that I took from the xorg.conf and just posted above to highlight it even more. I'd suggest editing your screen section and adding a virtual line for the resolution that you want to run, so based on what you posted before, your screen section would look like: Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" SubSection "Display" Virtual 1280 1024 EndSubSection EndSection and see how you get on. Will require a restart of xorg to do this, so a simple CTRL-ALT-BACKSPACE will sort this out unless you prefer to fully reboot the system. You'll then need to go into screen resolution and see if you can change it and get it to go higher. Not guaranteeing that this will work, but just an idea. I can't go to 2704x1050 anyway, but all I can think of, unless a modeline would do the trick. You could always try the detect displays button also to see if it changes anything and gives you a higher resolution to use. Quote Link to comment Share on other sites More sharing options...
scarecrow Posted December 23, 2008 Report Share Posted December 23, 2008 (edited) Don't waste your time... This version of Mint is using the latest Ubuntu base, and xorg-server 1.5X, which simpy ignores the xorg.conf settings. Whatever you may want to do to change the default behaviour, you MUST change the HAL settings. Or, alternatively, you can add to your /etc/X11/xorg.conf (if this thing exists right now) a section like that: Section "ServerFlags" Option "AutoAddDevices" "False" EndSection This will disable input hotplugging, and make your xorg.conf settings being respected.

adamw Posted December 24, 2008 Report Share Posted December 24, 2008 ...but your monitor is not an input device. The problem is not input hotplugging, which is irrelevant here, but RandR 1.2-compliant drivers. These don't use the old xorg.conf format for specifying preferred resolution and all that jazz, they'll happily ignore it. You can, however, specify preferred resolution in a way that RandR 1.2-compliant drivers should accept.
