From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.2) Gecko/20040308 Description of problem: I have several Linux machines networked together. For the problem that I am reporting, I will talk about the one that runs RedHat Linux 9.0 and the one that runs Fedora Core 2 (recently installed). I use ssh to connect from one machine to another to run GUI based applications. When I ssh from RH9 to FC2 and run a graphical application, things work fine. When I ssh from FC2 to RH9 and run a graphical application, the application works, but I receive the message shown in the example below, and I notice that things run more slowly. RH9 is running on an AMD 2400 w/ 1 gig RAM, nd FC2 is running on an AMD 2500 w/ 512 meg RAM, so I don't expect that the difference in speed is due to this small difference. Example: [alan@snoopy alan]$ kwrite & [1] 25078 [alan@snoopy alan]$ Xlib: extension "XFree86-DRI" missing on display ":0.0". libGL error: failed to open DRM: Operation not permitted libGL error: reverting to (slow) indirect rendering Xlib: extension "XFree86-DRI" missing on display ":0.0". libGL error: failed to open DRM: Operation not permitted libGL error: reverting to (slow) indirect rendering When I installed FC2, I downloaded the iso's, installed them, and ran up2date to get all updates. At this point, all updates have been applied. I last updated RH9 when the updates were still being released. I personally have made no changes to the X configuration on either machine, so all settings should be what came along with the installation or any updates from up2date. kinfocenter on FC2 reports vendor release number 60,700,000; version 11.0 while it reports vendor release number 40,700,000; version 11.0 on RH9. Any help would be appreciated. Version-Release number of selected component (if applicable): 60,700,000 How reproducible: Always Steps to Reproduce: 1.While running X on FC2, ssh from FC2 to RH9. 2.Start any GUI application (e.g., kwrite). 3.The message is immediately displayed on the konsole. Actual Results: The GUI application runs, though it runs more slowly than expected, presumably due to the slower rendering. Expected Results: The 'Xlib: extension "XFree86-DRI" missing on display ":0.0"' message is not displayed when ssh-ing from RH9 to FC2. I am hoping not to revert to indirect rendoring when ssh-ing from FC2 to RH9. Additional info: In the example below, I have already established an ssh session from FC2 to RH9. [alan@snoopy alan]$ kwrite & [1] 25078 [alan@snoopy alan]$ Xlib: extension "XFree86-DRI" missing on display ":0.0". libGL error: failed to open DRM: Operation not permitted libGL error: reverting to (slow) indirect rendering Xlib: extension "XFree86-DRI" missing on display ":0.0". libGL error: failed to open DRM: Operation not permitted libGL error: reverting to (slow) indirect rendering
This is because KDE didn't use to ask for DRI. KDE now asks for DRI and causes this message to occur on every program startup it does. Its harmless and basically a complicated way of saying "remote applications cannot use hardware direct 3D acceleration"
Thank you for clearing this up for me. I appreciate it!
