Sorry, after an extensive search through all these foruns, I decided to post my problems here! Maybe it's not the better place but I ask for your comprehension on it!
I've a derivative of Knoppix (Kurumin 4 - brasilian distro) installed in my machine, dual boot with XP. I removed the entire KDE and kdm as well and installed GNOME and gdm which I prefer. All went well, I received and installed all the packages needed through Synaptic and I was happily working on it (drawing with Inkscape, using Gimp, OpenOffice, burning CD's with Nautilus, watching videos with Xine, the all thing - I was forgetting Window$ :-D )
After a while I realize 3 things where not ok and I can't figure it out (remember, I've searched a LOT before I post here but never found a solution to any of these problems):
1) the most serious - I can't reboot or shutdown from Gnome. I see all the options there when I click on the exit button but every one of them take me to the login screen. Question: what is going on? How can I have my machine restarting or poweroff normally? In KDE this just worked fine! Should I return to KDE, is that it?
2) I can't use Alt and Alt Gr keys and I need them to insert special characters of portuguese language, for the "euro" symbol and "at" symbol. Please, I'm not entirely new to this: I already went to keyboard layouts, portuguese is chosen as default; my XF86Config-4 file has the xrules and the xkbdlayout set to the right values
Option "XkbRules" "xfree86"
Option "XkbModel" "pc105"
Option "XkbLayout" "pt"
but nothing seems to work
3) finally, in Gnome Control Center I use power management and I set standby to 10 min, suspend to 60 min and poweroff to 90 min but it doesn't work. I spent far more than 10 min away from my PC and when I got back I realize it didn't use the power management feature...
Can anyone help, please? The first problem is really anoying me because I have to use the On/Off button of the pc and that's not very «recomendable»... please, please help
