ok… I was trying to install the wrong BIOS the E1781IMS.310 is for i7-5xxx while mine is i7-4720 . So I needed a E1781IMS.310T
$ cat /proc/cpuinfo | grep "model name" | head -n 1 | cut -d ' ' -f 5 | cut -c 4 4 the bios is upgraded !but I still have this issue. I tried the 349.16 free driver instead of 352 but the issue is still the same. $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date E1781IMS.10T 05/19/2015 ** Changed in: xorg (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1467609 Title: vibrations on MSI gt72 2qe scren To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1467609/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
