--- Comment #29 from Vesa <[email protected]> --- My VGA cable has ferrites on both ends and connectors are well secured. I have not seen this problem with Windows, nvidia or vesa (not me) driver. Even now with Ubuntu 10.04 and nvidia driver the screen is perfect. I attached a new photo. It shows horizontal lines when nothing changes in the screen contents and the hard disk is idle. I am an embedded software programmer. I think this might have something to do with graphic adapter bus timings. Once I had an AD converter board which had periodical errors in DMA transfers when wait states were not set correctly. This graphic adapter shares memory with mother board and I guess it picks other memory bus traffic. This might not be shown if graphic adapter has an internal memory. Do you yourself have a geforce 4? -- You are receiving this mail because: You are the assignee for the bug.
