Nvidi cards have given me issues with Kubuntu Karmic (9.10) also but it has
been inconsistent. On a 128 bit card at least 2 years old it works
magnificently at 1600 x 900, however on another computer, AMD 64, a new PCIe
card won't save the resolution and tops out at 13xx by 7xx (can't recall
exact figures) both using the non-free Nvidia drivers!
That isn't the most puzzling display issue I'm working on however. On my 2
year old MSI Wind U100 every version of 9.10 I've tried (Ubuntu, Kubuntu,
Ubuntu, Mint etc) has the 'flashing brightness' problem that never occurred
with any previous Ubuntu, or any other distribution. Yes I have searched
the forums and net extensively but have only found partial and temporary
solutions. Before I start to move (temporarily) beyond the Ubuntu family I'd
like to appeal for help with this.
