Hello Aaron,

Thank you very much for your reply. I can't see an option in my BIOS for disabling NVIDIA. Have you got any idea where I should look at in the BIOS settings?

I fixed the library problem, but the error message still shows at staring lxde.

Hi Martin,

Thanks for trying with dfly :)

DFly doesn't have any (KMS) Nivida GPU support, and your laptop seems really
old (i.e., without UEFI), so I don't think the xf86-video-scfb work for you.

If you can disable the Nvidia GPU (in BIOS) and use the integrated Intel GPU,
it would be the best for dfly.

There are quite some users and devs running dfly as a desktop, and XFCE and
MATE (I'm not sure about other DEs) should work well.

There is a known library problem with polkit
(/usr/local/lib/polkit-1/polkitd), which causes problem for dbus, but I don't
know whether this problem is related to your issues.

To workaround the library problem:
# cd /usr/local/lib
# ln -s /usr/local/lib/ /usr/local/lib/
