From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.16-22 i686) I have a laptop with the ATI Rage Pro LT (8 MB) video card, on which I installed RedHat 7.1. When I start any KDE application at the prompt (konsole, for example) I get this error message: Xlib: extension "RENDER" missing on display ":0.0" Reproducible: Always Steps to Reproduce: 1.start any KDE application at the shell prompt (kppp, konsole....) 2. 3.
Not all drivers implement this extension, and you have one of them. To avoid this message, turn off anti aliasing in the KDE control center.
I have the exact same problem. However, I'm using gnome !! Under the gnome configuration tool, I could not find an 'anti aliasing' setting. Can anybody tell me where to look, or what to do in this case ?
GNOME does not use Anti Aliasing whatsoever. Something is trying to use the RENDER extension on your system and your drivers do not support it yet. THe only thing that uses Render I believe is Qt, and xterm. Make sure AA is turned off in the KDE control panel (yes, you can do this from GNOME). Make sure xterm is not using AA fonts. If that does not work, please use the xpert mailing list.
