HELLO, I met this question when I finished the installed of Ubuntu 14.04 on jetson jk1 board.
The menu of windows and the dialog change their size automatically, and the menu even hide and show automatically. Meanwhile, the mouse blinking.
I have reinstalled the system and remove the indicator-desktop package, but change nothing. Also I changed the environment to kde-plasma-desktop, but there is no launch in it, so I change it to ubuntu-desktop again.
I also have checked the display in system setting, there is only one display.
Thanks who help me.

Check your graphic card and its driver first.

Refer to this page for adding some suitable kernel options into grub 2 boot menu :

It will be a workaround to login your desktop, then Check your graphic card and its current driver.

too small，can not see

Thx,
I input the command, there is the output follow:
NVIDIA Corporation Device 0e13 (rev al)
CI Express Gigabit Ethernet Controller (rev 0c)
I want to use nouveau as the drive, and donnot want to use nvidia.But I have no idea how to check my drive info.
And when I run
, there is no result.
There is the info in xorg.conf

I see the same problem,but the solution doesnot work for me.

1. lspci ?

2. That is because the proprietary driver nvidia was still not installed.
