** Description changed: Laptop Lenovo Y50-70 (Kubuntu) Description: Ubuntu 15.04 Release: 15.04 Linux L 3.19.0-21-generic #21-Ubuntu SMP Sun Jun 14 18:31:11 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Xorg freezes (i think so because kill Xorg helps). There are 2 GPU's in the laptop . No matter which driver is enabled. After a few minutes the whole system does not longer react except the mouse-cursor . the control bar. Alt + Tab works >=twice , then you can only kill Xorg (trough strg+alt+f1 or so). Then lightdm shows up, i login to be able to repeat the whole process a few minutes later. have tried all available drivers nouveau, nvidia(340,346), intel+nvidia trough bumblebee right configured, purged all nvidia and bumblebee and only nouveau NOTHING HELPS :( . It come ACPI errors and if I start with the Nvidia driver vgaarb error's the freeze is accidentally. I cannot say now the freeze comes sometimes it takes minutes sometimes seconds after login. I think it must be something with the driver maybe bumblebee but as i said i removed the package's already and the problem persists. Maybe ACPI state? + Kubuntu 14.04 was working better not perfect but much better. + My other operating system (windows 7) is operating perfect. But actually I prefer linux for many reasons. (really sorry about my "bad" English) f something is not clear , I will definitely try to improve my formulation.
