I am having this same issue under KDE3, after having installed, and uninstalled KDE4. I even tried uninstalling and reinstalling KDE3, but the problem persists.
After I login to a KDE session after about a minute or so, KDM all of a sudden goes to full CPU usage. This is also on a Vostro, but I believe it's a Vostro 200, though it is also a Core 2 Duo. This is on Hardy, 8.04 I believe this is an onboard Intel graphics system, with default drivers. For a workaround I have switched to gdm -- kde4 kdm uses 100% of a cpu core https://bugs.launchpad.net/bugs/204147 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
