Cannot get higher screen resolutions to work

stony999 · Post by **stony999** » 21. Jul 2008, 16:40

Hello,

I have a problem getting horizontal resolutions higher that 1280 to work. It always switches back to 1280x768, although I can select a monitor with 1400x1050 and select the same resolution in displayconfig.gtk (Ubuntu 8.04)

The vboxvideo drivers are loaded but in the log it says:

Code: Select all

(II) VBoxVideo(0): Output VBOX1 has no monitor section
(II) VBoxVideo(0): Output VBOX1 connected
(II) VBoxVideo(0): Output VBOX1 using initial mode 1280x768

This is strange as a monitor section is defined.

Just to mention: The linux client runs via RDP and the resolution of the "Terminal Server Client" is set to 1400x1050.

Any hints?

Here is my xorg.conf

Code: Select all

I got stuck at the same point, also having a xorg.conf with a number of entries, and was unable to obtain better results.

I was able to obtain better resolutions in the following fashion.

* log in (entering a 1280x768 graphical mode)
* open a terminal (Applications -> Accessoires -> Terminal
* give the command 'xrandr' (minus the quotes of course) to obtain the available modes
* give the command 'xrandr -s 1680x1050'

And the screen resized to the desired resolution.
Below, the contents of my terminal are displayed

nfsadm@ubuntu-virtual:~$ xrandr
Screen 0: minimum 64 x 64, current 1280 x 768, maximum 32000 x 32000
VBOX1 connected 1280x768+0+0 0mm x 0mm
1280x768 60.0*+ 60.0
1680x1050@60 60.0
1600x1024@60 60.0
1440x900@60 60.0
1280x800 60.0
1280x800@60 60.0
1280x768@60 60.0
1280x720@60 60.0
1024x768 60.0
800x600 60.3
800x600@60 60.0
800x600@56 60.0
640x480 59.9
nfsadm@ubuntu-virtual:~$ xrandr -s 1680x1050
nfsadm@ubuntu-virtual:~$

Of course, once you know what modes are available, it is faster to log in, use <ALT><F2> for a command prompt, and enter 'xrandr -s 1680x1050' there.

It should be solved in 1.6.4 that is released today. Please check if it still occurs. Be sure to update the GA too.

Perfect, I installed 1.6.4 and the addons and after installing the addons the new modlines worked.
I now have resolutons up to 1672x980 which fits inside an 1680x1024 Gnome screen.

FYI here are some modlines I used:

Code: Select all

Modeline "1400x950@60" 113.49 1400 1432 1856 1888 950 969 979 998
Modeline "1496x950@60" 120.93 1496 1528 1984 2016 950 969 978 998
Modeline "1648x950@60" 132.71 1648 1680 2184 2216 950 969 978 998
Modeline "1648x980@60" 138.27 1648 1680 2200 2232 980 1000 1010 1030
Modeline "1672x980@60" 140.21 1672 1704 2232 2264 980 1000 1010 1030
