I previously ran F9 with no problems at all. This morning I upgraded to F10 using preupgrade, and all seemed to go OK.
But now some of my keyboard mappings don't work. The arrow keys don't work at all. PgUp now types a forward slash, PgDn appears to have the same effect as right-clicking on something. There are some other ones that are either wrong or non-existent, too.
The first thing I checked was my Gnome keyboard config. It reckons I have a Microsoft Natural Keyboard Pro USB with UK layout (which is correct). This is the same keyboard that worked fine under F9.
Then I looked at my xorg.conf which also appears to be OK. Just in case it helped, I tried commenting XkbLayout and XkbModel but this has no effect.
# generated from data in "/etc/sysconfig/keyboard"
Option "XkbLayout" "gb"
Option "XkbModel" "pc105"
Has anyone else come across anything like this?
