Operating Systems HP-UX Configure X windows with both keyboard and USB barcode reader Post 303041220 by mnkaltenbach on Monday 18th of November 2019 05:26:17 PM
The X log files are located in /var/X11/Xserver/logs/. A long listing of the directory looks like this:

-rw-rw-rw- 1 daemon daemon 3313 Nov 8 16:12 X0.log
-rw-r--r-- 1 root daemon 138 Nov 8 16:12 Xstartup.0.log

Again, no error info appears in either of the logs. The X0.log even contains the entry "Fri Jul 5 14:47:58 2019: /usr/lib/X11/extensions/hp7lc2k.1" conveying that the added lines to /etc/X11/X0devices resulted in the hp7lc2k.1 driver being loaded but the USB barcode reader not work together with the keyboard.
