xmodmap: right alt remapped to right control has issues with shift

[Steven Thomas]

Binary package hint: xorg

I like to use xmodmap to remap the right alt key to control. What I find is that (starting in Ubuntu 10.04), pressing shift before I press the remapped right alt key causes the right alt key _not_ to activate with a modifier (it should be right control). Here's the sequence of key presses and the effects I see in xev:

<shift pressed>: keycode 62, shift_r
<with shift still held, right alt pressed>: keycode 108, no symbol

If I don't press shift first, I see this:

<right alt pressed>: keycode 108, control_r

Below is the xmodmap file I'm using to remap my keys. I also remap caps lock to control, and that key has no problems with shift. I load this file up with 'cat my-xmodmap | xmodmap -'.

>>>>>>>>>>>>>>>>>>>>>>>
! Map right alt to right control
keycode 108 = Control_R

! Map caps lock to control
keycode 66 = Control_L

clear Lock
clear mod1
add control = Control_L Control_R
add mod1 = Alt_L Alt_R Meta_L

As I mentioned, this worked fine in Ubuntu 9.10 and earlier.

Hi Bryce, are you sure this is related to the Nvidia graphics driver? IIRC it was also happening on my Intel graphics based laptop, but my laptop's busted right now and I can't confirm that unfortunately.

I double checked, and the issue is the same on my netbook with Intel integrated graphics (asus eeepc 1005peb), so I doubt it's related to the nvidia graphics driver.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
