Lockscreen graphical glitches Ubuntu Gnome

I've been using Ubuntu Gnome for a couple of months now and in the lockscreen I get these weird graphical glitches. First it started with the arrow that tells you to drag up to login, and then the whole lock screen. One time it also effected the desktop once I logged in. The issue seems to be happening on Gnome 3.14 and 3.16 with Ubuntu 14.10, 15.04 and Debian 8. I am using the Nvidia drivers, but I think it happened before installing those using the nouveau drivers. Laptop is a Lenovo Ideapad Y500 with dual GT 650M GPUs (no SLI due to Nvidia drivers)

Anyone here having the same problem?

I don't know if anyone replied to you personally?
However i am running ubuntu 15.10 wily, with gnome 3.

Everytime i set my lockscreen background, it works perfectly, however after the reboot it is just a gray messy pixel landscape.

I tried googling for the answer, but to no luck.

Looks like the Test pattern of the Apple 2c. I was just watching a video by "The 8-bit Guy" where he was refurbishing an Apple 2c and your pattern reminded me of it. I also have had similar patterns on different pcs dating back to the 90's. Try disassembling it and reconnecting all of the ribbon cables and slotted chips more securely. Poorly connected component's can trick a pc into basic testing mode by bridging the wrong way. If your laptop monitor has a loose connection then closing and opening it can really mess things up, including the lock screen.

I believe you are responding to the O.P.
Because the problem i am having is a software based problem i believe.

However cool video, i love seeing old hardware.
May i also direct you to a more geeky/weirdo youtube channel, i have watched this guy doing all sorts of weird stuff with old hardware, apples, dos, windows 95, ssd's and now an apple server.
He is called Drauga1 on youtube.

Any how i hope the problem of step1041 will get solved.

Kind regards,

I don't think that problem ever did get resolved. That was about a year ago when I was distro hopping so there may have been a fix since then. I think I just gave up and only used nouveau drivers and didn't bother with the proprietary ones.

That laptop ended up having other graphical glitches that I think are related to a failing GPU. At the end of August I finished school and didn't need the laptop for day-to-day work so I put it into semi-retirement. It just sits on a table running Windows 7 in a KVM that I can remote into as needed. Its headless so I don't need to look at the screen.

I bough the second GT 650M aftermarket from Lenovo but didn't buy a new power supply for the laptop. So it has probably spent 2 years starving for power which may have caused some problems in the GPU. The laptop in general wasn't very well built anyway. Now I just use my old MacBook pro as a day-to-day machine. Almost 7 years old but works well for RDP and web browsing.
