i can use Linux 3.13.x kernel (im currently running 1.3.0-32 from Trusty while writing this). Once i upgraded to 1.14.x, and i couldnt use my PC. same symphtoms.
it seems that kernel does not get monitor resolution properly, but im not good at coding, so i cant say what the reason is...
Now, i have recently upgraded to Utopic, and i cant use 1.16.x kernels too.
I have 2 laptops, and this desktop PC
My laptops have an AMD Radeon HD 5143 and an AMD Radeon HD 8400 (integrated into an AMD A6-5200 CPU). Both are working correctly.
My desktop PC (the one that fails) uses an AMD Radeon HD6570 PCI-express, with an Intel Core i3-530
Each computer uses the new 7.4.0 ati driver, so open source driver is not the problem.
