Installed 11.4 on my 2005 Toshiba Sattelite Pro L10 - 1GB & P3 1.6 - and very soon after loading the display flickers erratically and blacks out or renders transparent portions of windows. Menus flicker, controls become inoperative and it is unusable. It has an Intel 855 graphics chip, desctibed in another post as a ‘linux killer’ for some reason I don’t know.
No woes with other distros on this machine, ever. I’d love to look at logs, try for an updated driver or whatever but it can’t be used. I ran the download ISO inside VMware Fusion before installing and it had no probs with that, thus it seems that the d/l is OK, at least.
Please, any solution(s) before I overwrite and dig out Ubuntu?
Same here on a Dell Inspiron 700m. However the display works fine when used as a remote X display, so it seems to be something to do with the desktop rather than the X server. This laptop has never needed special boot settings so I doubt if it’s nomodeset. I’d be interested to see how this pans out.
Disable ‘Display management change monitor’ : is this ‘nomodeset’ in GUI format?
Happy to hear of your success pofadda. That report about KDE4 was made is 2008 and is pretty old. It is hard to say if it would still apply to KDE 4.6 but deano_ferrari did determine the new way to disable the function is with *System Settings >> Startup and Shutdown >> Service Manager >> Disable ‘Display management change monitor’ *but I am inclined to stick with the nomodeset kernel load option myself. As a relative new forum user, I always add a few more things for you to look at.

Unfortunately neither solution works for me. nomodeset disables the external display and I cannot switch to it with Alt-F8 (exact key depends on computer model), so while it may fix the internal display, it’s not a workable solution for me. Turning off the Monitor display changes also has the same effect but takes effect after X has been started. Since this laptop works fine as a remote X display at the moment and I have no plans to take this machine elsewhere, I’ll just wait and see. It seems the software is confused by having two displays, one builtin and one external, that’s the situation that is different in my setup.
I doubt if it’s the kernel. I think it’s either the desktop or the X server. There has been a regression from 11.3. And I think people are resorting to mystery workarounds instead of understanding what the problem really is. My theory is that since KDE 4.6 now has fancy translucency, the X server is advertising capabilities it really doesn’t have to the desktop.
Unfortunately time is not something I am willing to devote to this problem. It isn’t blocking my work as I’ve explained, and worst comes to the worst, I’ll revert to 11.3.But I’ll keep an eye out for more evidence.
