What is in your mkinitcpio.conf? In /etc/modprobe.d/? /usr/lib/modprobe.d?

@samanmohamadi
Copy link
Author

There is no mkinitcpio.conf in /etc/modprobe.d/ and /usr/lib/modprobe.d/ but content of /etc/mkinitcpio.conf is :

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="i915 nvidia nvidia-uvm bbswitch"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect block filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev block filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev block mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev block lvm2 filesystems"
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block filesystems keyboard fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=""

There is some other info of my system configuration in this thread :

Sorry I didn’t state it clearly, I was asking for the content of those folders.

Please remove rcutree.rcu_idle_gp_delay=1 from your kernel boot parameter (not needed anymore since 3.19) and nvidia, nvidia-uvm & bbswitch from MODULES in mkinitcpio.conf and then rebuild the initramfs.

Also, provides content of /etc/X11/xorg.conf.d/ if it still doesn’t work.

Did you ever find a solution? I am having the same exact issue after having tried the same suggestions you have.

No , if you found any solution please inform me too.

I've just done a clean reinstall of Arch and it works as it used to. Best of luck to you.

@samanmohamadi Sorry for the long delay without answers. If you’re still having this issue, could you please report content of /usr/share/X11/xorg.conf.d directory (and of the files within obviously)? Thanks.

OK, I’ve removed unrelated content from your message. I’m quite sure of the problem now, but could you paste the full /var/log/Xorg.8.log file? Also, could you run pacman -Qo -Qo /usr/share/X11/xorg.conf.d/*? Thanks.

OK. Do you remember why you added /usr/share/X11/xorg.conf.d/20-intel.conf (normally it should use intel_backlight by default if accurate)? This is definitively the culprit. You should not have a user file there. I’m also skeptical with the presence of /usr/share/X11/xorg.conf.d/nvidia-drm-outputclass.conf, but if it’s an issue that would be a packaging one.

What you could do is the following:

  1. Edit /etc/X11/xorg.conf.d/20-intel.conf (with root or sudo permission) and add this after the “TearFree” line:
    Option "Backlight" "intel_backlight"
  2. Remove /usr/share/X11/xorg.conf.d/20-intel.conf.

Then try optirun again. Also, you might want to restart X (logout/in should do it) to check whether you have issue with backlight, but you should not have any.

Thank you , There is no TearFear line in 20-intel.conf, so I delete the the file but issue is still here:

[saman@saman ~]$ sudo optirun glxgears -info

[  256.933160] [ERROR]Aborting because fallback start is disabled.

Well, I’ve received your answer by email but can’t see it here…

At #653 (comment) you were having this file and line, but maybe you dropped it since. Anyway, if you have removed /usr/share/X11/xorg.conf.d/20-intel.conf and it still does not work, please post the content of /var/log/Xorg.8.log again.

You'r right ,I made maistake and opened wrong file There is TearFear line and I add Option "Backlight" "intel_backlight" after it.The 20-intel.conf is also deleted now.

OK, so that’s a new issue. Can you provide dmesg log? (if you didn’t rebooted since this log, then give the full log, else try run dmesg, optirun, dmesg and paste the diff)

That’s all? Nothing after that? No changes in /var/log/Xorg.8.log? :(

That's all.There is nothing new in Xorg.8.log :(

OK, so now we have to look at the other potential issue. Try the following:

sudo mv /usr/share/X11/xorg.conf.d/nvidia-drm-outputclass.conf /etc/bumblebee/

And then retry optirun.

No change, according to error, it's seems to be a permission issue, am I right ?

@ArchangeGabriel
Copy link

No, the permission error doesn’t matter normally.

Put the file back in place, remove every bumblebee related package including the nvidia driver, remove everything still present in /etc/bumblebee (and the directory itself). Then reboot, and after that reinstall the whole thing.
