video display corruption / 3dlabs permedia 2 / xfree 4 kde 3


My video display becomes corrupt in X as I work.. like static appearing on the screen, especially when scrolling or dragging windows.

Video card: 3d Labs Permedia 2
Xfree86 4.?
KDE 3.?
Mandrake 9.2

The problem is reproduced in all resolutions, although I've only tried the 24bpp modes.

The problem is reproduced at low clock/scan rates (i.e. 31.5 640x480 60hz) and at optimal rates. No difference.

My display works fine in Windows 98 which I have installed dual-boot.

I've tried enabling the no_accel option in XF86Config-4. Just slower display, no help.

Any ideas?

Thanks.

Ha! I solved it myself! I noticed that the first post in this forum about what info to post in your questions (which I read before I posted) talked about some "lspci" program which I didn't know what it was... well, I found it, installed it, ran it, and it listed three devices all using IRQ 11! (My video card, my ethernet card, and my USB bus.)

So with some fiddling in the cmos setup I fixed that. Interestingly, my cmos didn't consider this to be a problem... and neither did Windows 98... Also, my cmos didn't list the USB interface anywhere, and it showed IRQ 14 as available -- which when I tried assigning it made my system unbootable and I had to reset the cmos battery... but now I have my video on IRQ 9, and my ethernet on irq 15.

I hope this info helps someone else too.

I may have solved another problem that I didn't ask: I was initially using a usb mouse, and eventually it would stop responding, sometimes hanging the system. The log files referred to multiple attempts by Linux to reset the usb interface, to no avail. Since lspci showed the USB interface on IRQ 11 too, that may be now be solved, since it should have irq 11 to itself. The system has also just hung a couple of times...

Anyway ... yay! I was starting to think I wouldn't be able to run Linux reliably on this computer.

UPDATE: I spoke to quickly.

The problem DOES still exist.

The video corruption is MUCH less, but there is still some going on...

** Still looking for additional suggestions **

Thanks.

Same problem. Using a Permedia-2 based PCI video card as a secondary display in a dual-monitor configuration; first monitor works fine, but the Permedia-2 display has display corruption, which looks like white static or echoes or the mouse cursor and any open windows.

Turning down the sync frequencies helps, but at the cost of display quality. After turning down the vertical sync to 60Hz, there is no significant display corruption, but at the same time who wants to use a display at 60Hz?!

I've read that this problem can be solved by rolling back to XFree86 3.3.6, but that's not really a solution at all.

Anyone have any luck with this?

Hi 007,

Just me again. The only workaround I found, but also not a realistic solution, is to use the vesa driver instead of the glint driver. The vesa driver supports the standard resolutions at moderate scan rates (no non-standard resolutions or scan rates). This is my current setup. However, X runs MUCH slower with the vesa driver and this is just not worth it.

It's too bad that this decent video card doesn't seem to be supported by xfree86 anymore. Apparently the solution is to buy a different video card.

I am new to Linux and I have been banging my head against the wall with the same problem. Finally!! It's not just me. I am using a Diamond FireGL 1000 PRO with 8M, which uses Permedia 2. Still no solution other then buying a new card? I guess I'll have to shell out the dough.
