Hi folks.
I'm an Ubuntu user since 5-6 years. I have a problem with Ubuntu 12.10 x86. Problem is a little weird.
I can install 12.10 without any problem. My PC is working very well after first start. But..
When i want to shut down, star or restart my pc problems are starting.
1-If i want to start my pc, there is nothing to happen. Pc start bu there is no bios screen or smth like that. Then i can shut down pc pressing on power button for 5 seconds. After that i can start my pc without any problem.
2-If i want close my pc, ubuntu is closing but hardware dont close and freeze on purple screen. This situation is also happens trying to restart.
I havent any problem when i want to use Ubuntu 12.04, Linux Mint 13 and others.
This problem is also avaliable on Ubuntu 12.10 based OS. (Voyager XFCE, Mint 14, Xubuntu 12.10 etc..)
I googled and find a few problem posts but there is no solution. I think this problem is about Windows Secure Boot. I dont use any Windows. I installed only Ubuntu.
Thanks for reply..
My laptop is TOSHIBA Satellite A100-036(PSAANE-03K00RTE)
