Output of journalctl -b
I have an ASUS Q550LF running Arch Linux and KDM. I followed
https://wiki.archlinux.org/index.php/NVIDIA_Optimus but glxgears says I have do
not have any GLX support in X. I was asked on #archlinux on irc.freenode.net
for the output of journalctl -b and /var/log/Xorg.0.log
A knowledgeable person determined from this line
Jul 27 11:40:45 Kilimanjaro kernel: ACPI Error: Field [TMPB] at 274432 exceeds
Buffer [ROM1] size 262144 (bits) (20140214/dsopcode-236)
that there was a bug in ACPI and how that relates to detecting the video card.
I am not an expert, but I was also told by this person that this bug report
https://bugzilla.kernel.org/show_bug.cgi?id=60829 (Wrong ACPI handle is
detected for Acer V5-573G) is similar.
Because of that, I've also attached the output of acpidump and dmesg. In
addition, I've added the output of lspci. Is there anything else that you all
might need to investigate this?
