I just installed Ubuntu using wubi. The installtion went well but when i select to load Ubuntu nothing shows up on the screen. All that happens is my monitor switches from digital to analogue and then to hdmi, it just keeps doing that.

How can i fix this?

what graphics card do you have? Some require a workaround to get ubuntu to boot. http://ubuntuforums.org/showthread.php?t=1613132

I have an ATI Radeon HD 5700.

Should i add the nomodeset option to the kernal boot?

You could try that... then once booted, go to System, Adminstration, Hardware drivers and see if there is a custom driver available.

And if nomodeset doesn't work, try radeon.modeset=0 instead.

Neither of them worked.

All that happens is a splash screen comes up for a few seconds, a sound plays, and then the screen goes blank and it does the same as before. Switches from analogue to digital and then to hdmi.

There've been problems with certain graphics cards since Lucid introduced Plymouth. Nomodeset worked for me, but I have an older ati card.

What computer brand/model is it? Sometimes you can find solutions easier that way...

I thought of that but unfortunately doesn't work for wubi installs.

However, it might be the best approach if you want to get Ubuntu working.
(Also Wubi is good for trying out ubuntu but if you end up using it long term a direct install is better)

Ok, got it working. I had to start it in recovery mode using the nomodeset option in the command line. Then i had to boot in low-graphics mode and install a more updated driver. Only problem i have now is that the desktop does not fill the screen.

The resolution is set to 1920 x 1080 which is what i use in windows 7. I actually had the same problem in Windows and had to use the ati catalyst control center to fix it. What should i do?

Good tip on Wubi installs, seems it works best as a test run or temporary solution, but very unstable for long term.

Fixed the display now.

Went to System -> Preferences and found Catalyst Control Center, then went on the display manager and to adjustments and turned overscan to 0%.

I upgraded from 10.04 to 10.10 and have lots of graphics problems. I have ATI Radeon 3200 HD graphics built into the motherboard.

How does one use the "nomodeset"?

Originally had no display, then booted to recovery mode and used low graphics, installed the "ati-driver-installer-11-x86.x86_64.run" using the sh command line from a terminal window.

But now when I try to launch the catalyst control center I get an error message,


There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following.

No ATI graphics driver is installed, or the ATI driver is not functioning properly.
Please install the ATI driver appropriate for you ATI hardware, or configure using aticonfig.


Now Google Earth won't function at all, and I cannot logout or switch user, I have to reboot.
Any ideas?
