[Desktop-packages] [Bug 1278223] Re: Mouse Flickering after adding 3rd Monitor
Considering that newer graphics cards are relatively cheap, I fixed my graphic issues with a Gigabyte GeForce GTX 750 Ti WindForce 2X OC . Just wanted to leave a short note on the model so others have a reference on what works. Issues to consider: --- * no support in current Linux kernel of Ubuntu. I had to chroot multiple times while installing proprietary drivers.

[Desktop-packages] [Bug 1278223] Re: Mouse Flickering after adding 3rd Monitor
IMHO the flickering is caused by using 2 graphic cards for the unity desktop and not by connecting a 3rd Monitor. (seems to be consistant with previous posts ) I'm able to turn the flickering on / off by enabling / disabling my 4th monitor which is connected to my second "Radeon HD 6450" Setup: -- 1x Radeon HD 6450 -- 2x DVI BenQ GW2750 -- 1x HDMI BenQ GW2750 1x Radeon HD 6450 -- 1x DVI BenQ GW2750 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1278223 Title: Mouse Flickering after adding 3rd Monitor Status in “xorg” package in Ubuntu: Confirmed Bug description: My issues is, after adding a 3rd monitor to Ubuntu 14.04, the mouse flickers (or blinks) when the cursor is on monitors one or two, but not 3.

[Desktop-packages] [Bug 1278223] Re: Mouse Flickering after adding 3rd Monitor
After upgrading LTS from 12.04 to 14.04 I have the same issue. I have a 4 monitor setup with 2 graphic cards. I tried a lot of configruations / drivers, but the only thing that "worked" was completly uninstalling fglrx and connecting 3 monitors to 1 graphic card. Setup: -- 1x Radeon HD 6450 -- 2x DVI BenQ GW2750 -- 1x HDMI BenQ GW2750 1x Radeon HD 6450 -- 1x DVI BenQ GW2750 Result - Mouse Flicker on the 3 monitor system. No flicker on the 1 Monitor system. Funny thing --- When changing to gnome 3 or Xfce the flickering disapears -> Unity Bug? cat /etc/issue -- Ubuntu 14.04 LTS lspci | grep -i vga --- 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
