Escalated to Bugzilla from IssueTracker
Event posted on 06-22-2010 05:48pm EDT by Rezwanul_Kabir
Description of problem:
Due to Win7 requirement of using Win+P key to switch display, all recent Dell platform BIOSen are generating the same scancodes for Fn+F8 as with Win+P. The problem is they are not mapped to the right keycode used in linux for display switching ( i.e. KEY_SWITCHVIDEOMODE).
The scancodes for Fn+F8 and Win+P are as below:
0xe0 0x5b 0x19 0x99 0xe0 0xdb
[Key Press ] [ Key release]
The Keycodes for Fn+F8 press and release are:
125 press 25 press 25 release 125 release
Steps to Reproduce:
1. Install RHEL6 Snapshot6
2. Use "showkey -s" or "showkey -k" to verify
1. KEY_LEFTMETA + KEY_P are produced
KEY_SWITCHVIDEOMODE is produced
