Ubuntu Screen Resolution

Post by dew542512 »

Hi, installed Ubuntu 8.1 and the screen resolution is stuck @ 800x600 or 640x480. I've tried to detect my screen which supports 1900x1200 but no luck. Am i doing something wrong?

ps. read the manual - no joy ... I don't have the same problem with Windows 7 which I'm assuming is detecting my display correctly.

thanks!

have you installed guest additions correctly/successfully?
I can switch screen resolution to my MacBooks resolution afterwards. But Ubuntu does not remember the setting. I have to switch it after each boot of Ubuntu manually. But it works. Once.

Initially I also only got 800x600 or 640x480. I installed the guest additions and then got the choice of 1024x768, but nothing more.

Thus this dashes the hopes of running fullscreen on my 1440x900 screen.

Please see the Linux Guests forum for more info on this. You might need the vboxvideo entry in your xorg.conf file. And don't trust the Display options of your Guest. If you stretch the window, it should resize automatically.
Read the Forum Posting Guide before opening a topic.
VirtualBox FAQ: Check this before asking questions.
Online User Manual: A must read if you want to know what we're talking about.

Try this.

1. bring up the host OS' terminal
2. Type in VBoxManage global GUI/MaxGuestResolution any
3. Boot up Ubuntu
4. Go to the menu>Device>Install Guest Addition. Click on it
5. Disc image should appear on the Ubuntu desktop
6. Bring up Ubuntu's termina
7. Type in sudo /media/cdrom/ VBoxLinuxAdditions-adm64.run(This depends on your processor)
8. After finish installation, restart Ubuntu

Next time you boot Ubuntu, resolution in automatically adjusted to your screen's resolution.

Thanx
