Sanfod Rockowitz <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #7 from Sanfod Rockowitz <[email protected]> --- The backtrace is (almost) unremarkable. The libddcutil watch loop has detected an event of some sort and is checking the /dev/i2c buses for EDIOs. Some displays require a write before reading the EDID, so libddcutil first writes a single x00 byte to the /dev/i2c bus. The backtrace is from the ioctl() call to write that byte. There's no segfault, the backtrace just happens to occur in the ioctl() call. What would make it remarkable is if capturing the backtrace always occurs during the ioctl() call. What I need to see is the output of "journalctl -t org_kde_powerdevil -p debug", beginning with the most recent "Starting libddcutil" before the problem. The nvidia proprietary driver can be problematic, so the output of *sudo ddcutil interrogate" would also be helpful. -- You are receiving this mail because: You are watching all bug changes.
