Odd horizontal lines in Ubuntu but not in Windows


Recommended Posts

Hello

I have a stange bug that horizontal lines appear in Ubuntu (and Lubuntu) but not in Windows. They are like "tearing" and more of a graphics card problem than a graphic glitch as I can pass my mouse over them and the cursor still appears.

Whats wrong? I have a Quatrro graphics card on the notebook..

Thanks

are you able to take a picture of the scree while its displaying these lines, ive seen some what would appear to be the same thing

when trying to run Ubuntu on an all in one system. the problem turned out to be the timings for the monitor. ended up forcing

Ubuntu to use the screen but resolution was fixed and the display was not recognized by the OS.

I think I may have the same issue during a clean ylmf install on a ibm i1300 (installing all updates to see if it fixes this):

    • Closed-loop cooling and a custom 800G network protocol let the $7.3B campus run as one AI training machine. Microsoft confirmed June 23, 2026, that its Fairwater campus in Mount Pleasant, Wisconsin, is fully operational — and the engineering behind it makes the facility something fundamentally different from every data center that came before it. Where conventional cloud infrastructure racks up general-purpose servers and parcels out workloads to each one independently, Fairwater links hundreds of thousands of NVIDIA GB200 Blackwell GPUs into a single, coherent cluster using a two-story building design, 800-gigabit-per-second Ethernet fabric, and a proprietary networking protocol co-developed with OpenAI and NVIDIA. The result, according to Microsoft, is the closest thing to a purpose-built AI supercomputer that any company has ever placed in commercial operation. https://www.techtimes.com/articles/319205/20260627/microsoft-opens-fairwater-wisconsin-ai-campus-runs-one-supercomputer-via-800g-ethernet.htm
