Ubuntu shaky display problem

rated 0 times [ 0] [ 0] / answers: 1 / hits: 2536 / 1 Year ago, fri, november 25, 2022, 5:15:58

Good afternoon, I recently got the lenovo y70 touch laptop and got it ready for Linux, however, Ubuntu has a display problem where the screen looks like it's shaking or tearing, I've tried nvidia drivers to no avail. The strange thing is that on distros that don't support touch out of the box like crunchbang and elementary OS don't have this issue, but have a lot less out of the box features compared to Ubuntu so I'd rather use Ubuntu. Any ideas?

Upgrade to kernel 3.18 — or 3.19, see below —, that solved the problem for me.

I have a Lenovo Y70, like you. And Linux Mint 17.1 which is based on Ubuntu 14.04. Installing the latest NVIDIA drivers had no effect, only upgrading to kernel 3.18 worked. Kernel 3.16 didn't work.

Unfortunately, my wireless network card doesn't work with 3.18 :-( So I just installed kernel 3.19. That one seems to have solved both the shaky display issue, and works with the Y70 wireless network card. So the fourth kernel I tested worked :-) Last time, with Linux Mint 17, I had to try 3 different kernels before the network card was happy.

This is how I installed 3.19. Perhaps you'd need to use other URLs if new patch versions have been released.

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900-generic_3.19.0-031900.201502091451_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-headers-3.19.0-031900_3.19.0-031900.201502091451_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/linux-image-3.19.0-031900-generic_3.19.0-031900.201502091451_amd64.deb



sudo dpkg -i linux-headers-3.19.*  linux-image-3.19.*.deb

sudo update-grub  # not needed?

sudo reboot now
