• cannot login to gnome xorg

    I can;t disable touchpad, so I followed this:

    by running

    sudo pacman -S xf86-input-libinput
    sudo pacman -R xf86-input-synaptics
    sudo mv /etc/X11/xorg.conf.d/50-synaptics.conf ~/

    But now I cannot login to my gnome xorg.

    Then I copied 50-synaptics.conf to its original place, install synaptic and uninstall libinput, still cannot login to xorg.
    I still prefer using xorg, help.

    I found out maybe it’s because im using bumblebee and installing nvidia-setting and it edited my xorg.conf
    I commented the nvidia section in xorg.conf and i can login. But I only have low resolution. I want to reset my xorg.conf but I dunna what nvidia-setting do with xorg.conf

  • SOLVED but

    Solved by deleting xorg.conf but… is that ok? I mean… I was having xorg.conf before but now It’s gone. WIll it affect my system?
    I’ll mark as solved for now, … maybe

  • @Pegasusearl
    Using xorg.conf is deprecated and it shouldn’t be necessary in most setups.

    In correctly configured Nvidia Optimus computer with Bumblebee installed xorg.conf simply doesn’t exist. It is a normal, correct situation.

    Bmb uses two its own files, which are xorg.conf analogs, but they are called differently and are situated in Bmb folder structure, not in /etc/X11 folder.

    nvidia-settings utility, if launched in a not correct way, destroys Bmb configuration - by creating xorg.conf, which fools Bmb. It’s a perfect Bmb killer.

    The utility works with single GPU Nvidia cards only. It doesn’t work (when launched in default mode) for hybrid Nvidia cards.

    More info about Bumblebee may be found in AnteWiki here.

  • @just @karasu I think we should develop a GUI for managing graphics configurations (some day in the future).

    @just @karasu I think we should develop a GUI for managing graphics configurations (some day in the future).

    @karasu has already had a similar idea, almost a year ago. He has even started to develop nvidia-installer. It’s not easy, though possible.

    But covering all video cards, with all their existing modifications (Intel, AMD single GPU, AMD hybrid, Nvidia single GPU, Nvidia hybrid, BIOSes with and without hybrid cards control) is an ambitious goal. And a huge work.

    A GUI for all them would be as sophisticated as Cnchi itself, IMO.

  • @just Yeah I know, what I meant was that we should pick that work back up again at some point. But like you said, its crazy complicated to account for all the various setups. We will need help (mainly in the form of technical guidance as to what works, what doesn’t, etc from people like you who have the experience and/or have done the research) Of course coding help would also be welcomed should anyone be able to contribute on that level 😉

    Unfortunately, my work experience are 35 years on IBM mainframes, first under OS/360, later OS/390 and finally z/OS, mainly with Cobol 2. I’m rather unfamiliar with commonly used Linux scripts and languages. Can freely read and understand them, but my coding attempts are mostly a fiasco.

    An unexpected question. Is it easy to adapt Debian bash scripts for Arch?

    Many time ago, when I was on Debian, I wrote some articles, similar to our Bumblebee in AnteWiki, for KWheezy and SolydXK. SolydXK uses Device Driver Manager bash script to install the proper drivers on Intel, AMD single and hybrid, Nvidia simple and hybrid, and even on the Broadcom.

    I took part with testing and suggestions for the DDM part, which installs Bumblebee on Nvidia Optimus.

    It’s a stupid question, but maybe it could be easier to borrow the existing Debian code?


    Yes, I know that usually it’s easier to write a new program than try to modify an old one :) .
