GL Screensavers crash system
Last modified: 2007-04-18 12:32:03 EDT
Using XFree86-4.0.2-11 and rawhide March 5 version of others. Machines: Dell Dimension XPS T750r, DELL Inspiron 4000 1. Now KDM/KDE work on both machines - rendering fixed!? 2. GL screensavers, both from KDE (kscreensaver) and xscreensaver hang the system, everytime (no show) 3. Going to the rpms I built from February 19, 4.0.2 release BOTH the rendering and the GL work.
What video card do you have in the dimension? For the i4000, the XFree86-4.0.2-11.4.0 packages enable bus-mastering on X server startup which gets DRI working happily for the r128. If the Dimension has a Matrox card, the same fixes are present I believe and should fix DRI on it.
I have the NVIDIA GeForce 256 card on the Dimension. I am not sure where the -11.4.0 is. I can switch to NVIDIA drivers and all works fine of course. Again, GL also works with "nv" driver when I use Feb. 19 CVS tree. On the r128, GL does not work with -11 but works with my rpm from Feb. 19 CVS tree. DRI is enabled but I have not tested it. I am not downloading 4.0.2b, will build the new rpms tonight and see what they do.
Odd. GL should not crash the system with the 'nv' driver, as that doesn't even *do* direct rendering.
Probably I was not specific enough....I did not check if the system would respond to an external connect but essentially the X hangs, mouse still moves but doesn't respond to clicks and keyboard is dead. ctrl+alt+backspace and ctrl+alt+del do not respond either. But it does crash for some reason and it does not crash with the new X stuff. I built the rpm's with todays cvs again. Tomorrow I can tell more. Compared to -9 rpms -11 rpms did fix the Xft problem with kdm/kde (they both crashed with nv and r128).
The issue with r128 and DRI is fixed in 4.0.2-11.4.0 at: ftp://people.redhat.com/mharris/xfree86 Nvidia fixes to the "nv" driver will be going in soon also which may or may not fix issues with nvidia cards. The proprietary "nvidia" binary only driver is completely unsupported and will remain so indefinitely. Please do not file bug reports against XFree86 if you are using non- Red Hat supplied drivers as I cannot do anything about bugs with external drivers.
None of the stuff I am talking about referred to the propriety NVIDIA drivers but the nv driver. I know enough to not to file their bugs with you guys.
