Set Resolution

StaticSage · 07-23-2005, 06:11 PM

This computer is only used remotely. There is no physical monitor hooked up to it. I VNC from my windows laptop that shares its internet connection to the Ubuntu machine. I have a GeForce2 MX 100 DDR/200 DDR.

If I boot the computer with my monitor attached to it, it operates at 1280x1024 just fine. However, if I just have it boot with no monitor, it defaults to 640x480. Once I'm connected, the only option I have in System | Preferences | Screen Resolution is 640.480. I would like it to use 1280x1024 when I VNC to it.

I searched around a bit and saw this thread:
http://www.linuxquestions.org/questi...hreadid=337691

I didn't want to touch any of the files before I had someone else's opinion on it. Here is my xorg.conf if it will help:

Code:

if this is a real headless display, then i'd suggest not using a real X setup at all for vnc. just use the vncserver command directly with the -geometry setting to pick whatever size screen you want.

StaticSage · 07-24-2005, 10:01 PM

The -geometry added the 1280x1024 into the System | Preferences | Screen Resolution, which is great. It doesn't boot as that resolution, but I can at least change it now.

If I wanted to not use a real X setup, would I still be able to have things open if I'm not connected through VNC. Like if I open apps, will then still be open the same way when I come back? I'm going to try to read up on how to stop X from running, and just have vncserver start. I'll still accept help though.

I forgot to mention I'm pretty new to the whole linux thing.

in /etc/inittab change the default runlevel from 5 to 3 (or use some twiddly control center equivalent) to stop it booting. most systems will install a vnc service script (/etc/init.d/vnc or similar) which you can set to run on boot, and will often reference a config file like /etc/vnc for those geometry options etc... and using a vnc session it'll always be exactly as you left it when you return to it.
