Installation problems
« on: December 29, 2011, 05:11:13 pm »
Hey, I am currently a Windows user trying to install Ubuntu on my computer; however, every time I try the screen glitches up displaying random lines of colour on the screen during the installation process and splitting the screen in half once it is installed, rendering it unusable.  The unit I'm using is an Advent DT1411 and I'd just like to know if there are any known compatibility issues with this and if there is anything I can do to fix this, or another distro I could use instead. Thanks in advance.

Would I be right in saying the Advent Advent DT1411 has a Core i5 2320 (Sandy Bridge) CPU ?

Has it got an ATI Radeon HD6700M (add in) graphics card ? .. as well as a graphics adapter built into the motherboard (onboard) ?

If so, have you tried the onboard card ?

You are correct in everything you just said, but honestly, I have no idea how I would go about doing it. I don't really know too much about computers, but I'm doing my best to learn, so please excuse my ignorance.

From a quick search the problem seems to be related to the Sandy Bridge CPU containing an integrated graphics adapter (on-chip) that doesn't seem to be correctly switched off when an add-in graphics card is also present.

From what I'm reading there seems to be be a way round the problem, but I want to do some more homework on the issue before suggesting anything .. can you check back tomorrow night(ish), and I'll see what I can come up with :)

Can you answer me a question .. when you boot to an Ubuntu LiveCD, and select "Try Ubuntu", do you end up at a working desktop, or are your graphics still messed up ?

Ok, just got it working there now. It works fine, but the colours are still very glitchy; it is usable however.

OK, great .. can you hit Ctrl+Alt+T (at the same time) .. a terminal should open, in the terminal type:
Code: [Select]
sudo lshw -C display
and hit the enter key.

give the command a few seconds to finish, and post back what the output was.

be aware Linux commands ARE case sensitive, so that's a capital C :)

for clarity that's..
sudo lshw -C display

If you open a terminal and enter:
Code: [Select]
jockey-gtk

is anything listed under additional drivers ?

BTW, if there are any .. there's no point trying to activate them from the LiveCD .. I just want to know if there is anything listed.

Do you have a USB stick larger than 1GB and do you know how to create a LiveUSB stick with persisence ?

I want to try installing the fglrx drivers, but this can't be done on a LiveCD .. and I'd rather not try it on your hard drive installation till it's tested first.

I am actually using the LiveUSB at the moment, but I have no idea what you mean by the second bit
