Thank you for your attention. I took the following steps: (1) Closed Firefox. (2) Went to System > Preferences > Appearance > Themes, tried to change from my Custom theme to Human default theme. By this procedure, I could reproduce the 100-% CPU usage, fast increase of ACPI temp (from ca. 48 to ca 62 C) and partial X session hang (not possible to affect the "Appearance" window by using the touchpad). I dropped into VT and rebooted. I noticed for a second time that the Conky window appearance had changed (seems "normal" instead of "desktop", but restarting Conky restores my "desktop" setting). And the Human theme had an unusual hue too, I think, after reboot.
Next I changed the theme again, from Human to my Custom theme (I call it DustyFox because it's based on Dust, colours modified, with Foxtrot icons), without problems. In order to be able to post this, I will not experiment further, until I have submitted this comment... Nevertheless, this MIGHT be specific to my custom theme, or the community-themes package, containing Dust, Kin and New Wave. As I said, my DustyFox custom theme is based on Dust. Its window decorations are from the DarkRoom theme. Strangely enough, Kin seems to "infect" other themes with its remarkable colouring: even Human had this strange light yellowish tint after reboot. -- Changing theme causes 100 % CPU & hang https://bugs.launchpad.net/bugs/316575 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
