Hi, i have the same problem please take a look at the screen shot i have taken, the lettering has been replaced by strange symbols, and as other people my cpu usage goes to 100%, another note the graphs seems distorted.
hope this helps. i have a P4 3.20 ghz, with hyper-threading turned off, when turned on comes up as two cores, but that's another problem! ** Attachment added: "Screen shot of System monitor" http://launchpadlibrarian.net/13151550/Screenshot-System%20Monitor.png -- System monitor causes Xorg to consume 100% CPU https://bugs.launchpad.net/bugs/187383 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
