Description shuey 1999-04-13 03:32:01 EDT
Xsun (3.3.3.1-1.1 and 3.3.2.3-25) uses all available CPU
power when idle.  As soon as the screen blanks due to
inactivity Xsun jumps to using around 95% of the CPU.  When
the mouse is moved, thus powering the screen back up, the
CPU utilization drops to normal.  Oddly enough, if the
screen is reactivated by pressing a key on the keyboard the
CPU utilization stays high.  This behavior can be seen under
any 2.2 kernel.

what cpu architecture do you have / sparc system do you use?

Same problem for me on an LX(sun4m), with cgsix and RH 5.2.

Can you verify if the recent egcs*1.1.2-13 and kernel*2.2.5-21 errata
fix this problem?Can you verify if the recent egcs*1.1.2-13 and kernel*2.2.5-21 errata
fix this problem?

I have recompiled kernel 2.3.2 with egcs-1.0.2. This is on RedHat
Linux 6.0.

It seems like the bug has dissapeared.
Comment 5 Jeff Johnson 1999-06-01 16:15:59 EDT
This problem appears to be fixed by upgrading your sparc kernel to
the errata kernel*2.2.5-21.sparc*.rpms. Or use egcs*1.1.2-13 (or
equivalently egcs*1.0.2) to compile your kernel.

Thanks for verifying.
