I just changed from the proprietary ATI driver to Radeon (as a result of switching to kernel 3.16) and this bug now affects me. I'm pretty sure its the driver. I'm also using compiz. Not sure why LyX is so slow when other apps aren't, but a multi-Ghz machine should be able to keep up with how fast I can type.
Isn't it funny how hardware is at a blazing speed, but the "useable" speed is roughly the same as a few decades ago. Infact, I think my Atari ST could open windows faster than my Ubuntu box. Possible Workaround. If using Compiz, load ccsm and see if the Copy To Texture plugin is on. If so, see if turning it off helps. It seems to work for me. I'm wondering if LyX isn't reporting what part of the screen was damaged properly or something like that and its causing compiz to copy the whole window to the texture instead of just the damaged area. This would explain why a smaller window helps. I'm betting the bug only recently hit me either because the fglrx driver has a hardware speed-up for copy to texture or because I didn't have the Copy turned on before (I had to reconfigure a few things when I switched). Do we have any authors that can look at the code or whatever library is being used? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/353449 Title: lyx 1.6.x impossibly slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/353449/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
