Having issues with tint2 using the new kernel from Fedora 15? It's the same one from Debian.

$ tint2
real transparency off.... depth: 24
xRandr: Found crtc's: 2
xRandr: Linking output LVDS1 with crtc 0
warning : monitor not found. tint2 default to all monitors.
ERROR: battery applet can't open energy_now
Segmentation fault (core dumped)

I reported and fixed the issue for Fedora rawhide and 15. I also asked package maintainer Germán Racca to push it into the updates. If you cannot wait the workaround is to disable baterry "applet" (battery = 0 in the tint2 config file) or update to my build (only 32 bits - sorry).
