Ubunto 10.10 install/Screen Flickers


First off, What's up everyone, new to the forums... I'm a complete noob to Linux. I am in my first programming class and we went over some Linux stuff last night, I enjoyed it a lot and so I am trying to put it on my home desktop.

I couldn't find a search function on the forums so I'm sorry if this has been answered already:
I burned Ubunto 10.10 to a disk and when it goes to load I can see the Ubunto load up and ask me what language I want except the screen flickers like crazy.

my video card: ATI Radeon HD 5700 series

Thanks for any help in advance

here is the link to the short video: http://www.youtube.com/watch?v=4JNx0oKh1a0

When I'm going to install Linux for the first time on a computer I try several different distributions by means of booting the live CD/DVD to see which one works best with my computer's hardware.

That said, a flickering screen would suggest that the refresh rate on the Linux driver is too low. Do you have a CRT or an LCD monitor? It is also possible that Linux is loading the proper driver but it is not working properly.

I found the following web page.
https://help.ubuntu.com/10.10/instal...oot-parms.html

On that web page is the following information.
Quote:
debian-installer/framebuffer (fb)

Some architectures use the kernel framebuffer to offer installation in a number of languages. If framebuffer causes a problem on your system you can disable the feature using the parameter vga=normal fb=false. Problem symptoms are error messages about bterm or bogl, a blank screen, or a freeze within a few minutes after starting the install.
I'm not able to run the Ubuntu 10.10 installer right now so I'm not sure what part of the boot process would allow you to set that parameter. Generally you press the escape key when you see the first boot screen.

Still, if I were to encounter this problem during an installation I would try a different distribution such as PCLinuxOS or Linux Mint 10.

Thanks for the reply Stress...

I'm using a LCD monitor and I tried hitting Esc on the first boot screen and it didn't do anything. I guess when I get a bit more time i can try installing the mint like you said and get back to you. The reason I initially used Unbuto was because I wanted to save linux on my USB so I can take with me everywhere and Ubunto was the first thing that came up in google..lol

When I tried booting it from the USB, the screen still flickered of course and it was saying something about the ISO not being found or something so thats why I went to the disk.

Ok, I downloaded MINT and it did the same exact thing as Ubunto did.... If you look at the video in my first post, thats exactly what it is doing.

Well I've installed many distributions on many computers and I've never seen anything like that before. I guess if you live long enough ...

I don't know what to tell you.

lol..no doubt....Did you see the video? I think it's probably obvious that it's a video problem...I wonder if I call ATI, if they can do anything? It's not just you, I have posted on 3 other linux sites and everyone is just as speechless.

Appreciate the attempt at least man...ty
