Factoring out software leaves hardware. But yes, the manifestation seems strange. I've had similar but not identical problems in the past. * loose cable I'd discount that if you tied with a second monitor, the back and forth you 'd have made sure. * loose card. I know this doesn't apply with integrated systems * decaying motherboards The downside of integrated motherboards is that they are are 'all in one'. I've had the classic 'capacitor' failures; overheating problems and problems that emerge from that; solder joints oxidizing and undetermined deaths of motherboards. Laptops are prone to a further series of video problems. You don't say if this is a laptop or a desktop or what type of desktop (SFF perhaps), the vendor. You don't say if the video is integrated but I'd presume so from the lspci line. One simple test is to have a spare video board and try that. Disable the onboard and configure for the new board. But do perform a series of checks on the hardware, check cables & connection, visually inspect motherboard, check for hot-spots. The 'it doesn't happen at boot' suggests something in the class of a thermal problem. ------ I have a powerful laptop whose video has failed, but is too good an 'engine' to go to waste. its under my desk and runs, among other things, ownCloud, DNS, Squid ... I can still ssh to it and more to the point run X over ssh. http://www.vanemery.com/Linux/XoverSSH/X-over-SSH2.html http://unix.stackexchange.com/questions/12755/how-to-forward-x-over-ssh-from... (the above says 'you do not need to set any environment variables' but recent threads here indicate that may not always be the case!) A final test to see if this is a hardware problem .... within some bounds ... would be to ssh -X to it. What bounds? I'm not sure. It depends how you access the software. You don't need to log in as you would at a terminal if you are using the X11 authentication, but I'm not sure which libraries will be doing the rendering, which machines fonts will be used etc. Perhaps there are gurus who can tell you. However a remote login with ssh -X eliminates some of the hardware in the loop. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
