Good day to everybody

Could you please help me with this issue on my Nokia N9.
I have recently installed the TCPIpKeyboard from maemo.org but to install it i needed 2 packeges:
1. qtquickcompat_0.1.0_armel.deb
2. xdotool_2.20101012.3049-6_armel.deb

After the install of all packages the TCPIPKeyboard was installed without any problem.
But now I cannot use the next apps:
1. Browser (cannot be open)
2. Store (open the black screen)
3. Nokia Maps (open a Wight screen)
4. Ovi music (open a black screen)
And many other apps.

Also frequently I installed the packages:
libsdl1.2,
libsdl-mixer1.2,
libsdl-net1.2

Could anybody help me to find the resolution of this problem?

Thank you in advance and have a nice day!
