Mageia forum

Because of know issues of NVIDIA proprietary driver, I try to use nouveau from M4 distro. GUI started but screen content was corrupted.
For example, the lower taks bar is displayed only partially, basically as a shadow of taskbar. If the cursor is in taksbar area, it displays only the shadows of windows applications contained there. Launching the application, for example MCC also display only a shadow of MCC and the content of the window is displayed only partially, in places where a cursor pointer is present.
So I revert to NVIDIA proprietary driver.
Is any way to set proper work of nouveau?

the symptom you describe is one of wraparound

this usualy happens when the monitor is incorrectly identified and
refresh rate is way too high, or res is beyond the monitors capability.

this can be caused by driver, or just wrong options in Xorg.conf

but as usual you fail to share much info at all about your problem.

so graphics card please, xorg.conf please, and what environment you use,

and please what known issues of proprietry card driver are effecting you so bad you have to use
nouveu driver.

For the issues with nvidia driver, they can be easily fixed, see the update: https://wiki.mageia.org/en/Mageia_4_Err ... ry_drivers

Yes, it is possible to use workaround described here https://wiki.mageia.org/en/Mageia_4_Errata#nvidia_proprietary_drivers . But I use several non-supported by Mageia Community application for video streaming, transcoding and so on. Starting such apps using strace cause that that video content is choppy, So using strace is not right solution for me.

My video cad is C73 [GeForce 7100 / nForce 630i]

Maybe you should read the update there. strace is not necessary anymore, fix has been found.

Sorry. My fault. I did not read updates about NVIDIA driver.
Thank You for drawing my attention to it.
So topic can be marked as DONE

Well, it's not like I pointed you to the update already before ... *sigh*
