Hello, when I switch to vt while there is much drawing on the X Server (like KDE start) the X Server crashes after 1-2 seconds with SEGV. My setup: Linux 2.4.17, debian testing XFree86 Version 4.1.0.1 (no option to fbdev, the same resolution and color depth as set with fbset) The problem is the same, if I only use the first head. Hardware: Matrox G450, Athlon SMP I don't have the problem, if I use the mga X driver on top of matroxfb, instead of using the fbdev on top of matroxfb. But then there is a strange flickering when the X Server starts, so I prefer the fbdev driver.
You probably need more information, but I'm not sure what else I could write about this problem. Please let me know what else you need. I first wrote to Petr (the matroxfb mantainer) he wrote me the following: > I have no idea why it should die, on Gxxx neither video memory start > nor length changes on mode switch (it changes on MillenniumI/II), and > matroxfb does not steal framebuffer mapping from any app on console switch > (there are some plans to do that on 2.5.x, but as I disagree with these > plans...), only X itself unmap framebuffer itself. > So I think that it is fbdev problem - if you are getting kernel oops, > it is for sure matroxfb's problem, but if you are not getting them, it > looks to me like that fbdev driver tries to paint to screen even if > it is not visible (btw, mga-dri has same problem, it changes accelerator > color depth/screen width/height even if X are in background). regards, Roland Schulz _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
