after upgrading to 11.04, screen shows 'razor-type' diagonal lines, overlapping text, missing lines etc. which go away, when move (refresh) the page up or down. kernel version 2.6.38-11-generic. graphics card: mobility Radeon 9600 M10

following these instructions, I d/l ATI fglrx drivers 9-3-x86.x86_64, but never install completely. I get the msg -iscurrentdistro, then I try --listpgk and then --buildpkg Ubuntu/9.04 supposingly to build drivers for earlier version. But no matter what I do, the drivers never install completely: Get the msg

Errors were encountered while processing:

Read somewhere that this could be broken packages, and with synaptics tried to fix first 2 files that were broken, but then the error is:

cannot install fglrx-kernel-source....

tried to go back to the open source drivers as hereremove fglrx and install ati from scratch the drivers install, but the 'razor' effects, overlapping lines etc, come back.

By the way, tried system>administation>additional drivers, found fglrx drivers, but pressing 'activate' doesn't do anything.

Problem remains with Unity or Classic "view"
Is the kernel/card too old for both the open source AND the fglrx drivers?
Or maybe the buffer on the graphics card is messed up? t Thank you all


The Radeon 9600 is no longer supported by ATI after 10.04, if you can't use the open-source drivers then your best bet is to not upgrade.

  • ok clear better go back to 10.04 then thanks stanlex – user26620 Oct 10 '11 at 19:51
