Low Resolution with Ubuntu 9.10

[Sebastian Burch]

I added the changes to wrote on Xorg, but it didnt work. That isn't my graphic card or drivers.

[Heretical]

Sebastian do what gabak said. I had exactly the same problem with you. I am trying to solve it for a month now... and finally I can change my resolution! Gabak I love you. . And may I ask you something else. How can I have one more choice of 1280x1024 ? Thank you.

I did every step, and its fine until the last command

Code:


xrandr --addmode lvcd1 1024x768_60.00

Output:

xrandr: cannot find output "lvcd1"


Thank you.

Hey Seb,
Same problem here. Instead of LDVSs VGAs DVIs or whatever I used "default" and it recognized the output. Thing this happened afterwards:
"Failed to change the screen configuration!"
Hope u get better luck than mine...

It works fine now after create xorg.conf using the intruction by GABAK.

Why do you want to set the root password? I never have needed to do that on any system. If you want to run as root, then use sudo. You should never need the root password or a root desktop. If you want a root shell then use:

sudo bash

I installed Ubuntu 9.10 on an older system with a multi-sync monitor--a Viewsonic "PF790". I had an older nvidia adapter on that system. For some reason the nvidia install did not give me a monitor section in the xorg.conf file. The resolution was very low and I could not bump it up to 1280x1024. As a solution I had to add a monitor section and display subsection into my xorg.conf. Now I have the desired 1280x1024 resolution. I included the xorg.conf from that system below.

I added the Monitor line within the Section "Screen"
I added the entire Subsection "Display" in Section "Screen"
I added the entire Section "Monitor" to define the monitor.
Edit as you need for you monitor and system.
The HorizSync and VertRefresh settings came from the PF790 monitor specifications.
This worked perfectly for me.

Section "Screen"
	Identifier	"Default Screen"
	DefaultDepth	24
	Option	"AddARGBGLXVisuals"	"True"
	Monitor "PF790"
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Section "Module"
	Load	"glx"
EndSection

Section "Monitor"
	Identifier "PF790"
	Vendorname "Viewsonic"
	Modelname "PF-790"
	HorizSync 30-97
	VertRefresh 50-160
EndSection

Well, this problem is solved, for me!

I am really busy at the moment so I will post my solution's details later, but until then I can say:

-the 'xrandr' fix works as listed in the first page of this thread. just make sure you have a space between your mode name and the --addmode and --newmode commands. BUT, these changes will not be present after to reboot.

to fix it permanently, i used the Ctrl+Alt+F1 method to stop the gdm and use the xorg -configure command to create a Xorg.conf file.
NOTE: this method creates a "Xorg.conf.new" in your home directory with 9.10 karmic. to make it work, open this file as sudo with gedit, paste in gabak's code over the default code to replace it. then, save and rename to Xorg.conf, and move the file to /etc/X11/ -after I did this and rebooted I have all resolutions I needed.

the only thing I did different really was change the "1024x768" in gabak's code to "1366x768." now I have 648x480/800x600/1024x768/1368x768. all work perfect.

I can set my root password using: sudo passwd root.
Thanks anyway . .
