I tested with xosview 1.16 from upstream, but the bug is still present there (and I could find no bugtracker). Reproducible: Always Steps to Reproduce: 1. Start xosview +coretemp 2. 3. Actual Results: The display of xosview is not shown. Expected Results: I want to see the display of xosview. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
