First of all, as you will understand this post maybe should not be in hardware support...
Well, I have been using Linux Mint 12 in my Sony Vaio VGN-FW51ZF for a while, I've always had my Dead Keys working properlly... there was no problem.
Recently I had to write something in Japanese and I installed iBus as it was written in some guide most likely on this forum.
After doing so (when not using japanese alphabet) I could not use the dead keys, they would simple not generate any output.
After browsing google for help I got to the conclusion it was a known issue with iBus and there was not much I could do about it.
So, since I've had done what I wanted in Japanese and I did not intent to keep on writing Japanese in this computer I uninstalled iBus and rebooted.
Now my Dead Keys "work too well". When I press them I get immeadiatly the character.
(If I press ´ and after "a" I get: ´a
and not á as I should...) - I copied the right one from google just to explain.
This is a serious problem because I cannot write anything understandable in my language (portuguese) - I put this post here as there are many languages that need those characters regulary.
And, as I told you isn't exactly a hardware recognition problem because before installing and then uninstalling iBus everything was working as it should! (Howver I don't exactly know where should I post this )
I hope someone can help me...
Thanks in advance,
