Black screen at startup

patofet · 2014-10-08 22:29:30

Hello, I'm using Arch linux x64 3.16.4-1. I'm working on my computer and when I restart I only see(after the grub) a black screen with a blink cursor on it, and no graphical interface comes out(I use kde). I think that I don't update the system, only that can be is that I touch bumblebee(intel/nvidia GeForce GTX 860M) thinks(I change to bbswitch-dkms) and other thinks like that, the only think that I can do is Ctrl-Alt-f1 and go to the tty1, if I try "startx" I get this log file(/var/log/Xorg.0.log):
https://drive.google.com/file/d/0B0wswR … sp=sharing

if I see the kdm status(systemctl status kdm):
X server sied suring startup
X server for display :0 cannot be started, session disabled

If I try "startkde":
$DISPLAY is not set or cannot connect to the X server.

I try to put nomodeset or/and rcutree.rcu_idle_gp_delay=1 as kernel parameter at GRUB but doesn't work.

Anyone can help me please?
Thanks

I'm having the same problem, and I have a desktop with a single nvidia card, i.e. no optimus or bumblebee.

I use KDE with KDM. Tried restarting the KDM service, and even using xinit with "exec startkde", and I had no luck.

Also, tried reinstalling the nvidia driver and rebooting.

I presume you mean:

I think that I didn't update the system, it can only be that I touched bumblebee(intel/nvidia GeForce GTX 860M) things (I changed to bbswitch-dkms) and other things like that

Only you know what you do with your installation. I suggest you undo what you've changed, coming back to a previous state where everything worked.
If you can't do that, it will be difficult for anybody else to do it for you and help you efficaciously; maybe someone using bumblebee... (I don't).
Good luck.

I figured out the problem in my case.

The problem was that my card (GTX 260) was not supported by the version 343 of the "nvidia" package, so I had to replace by the legacy version of the package "nvidia-340xx".

Lucky you are. I've got the same blinking cursor problem with Nvidia (KDE). I tried the following:

(1) Downgrade to nvidia-340. No luck (Nvidia GT218).
(2) Revert to the Intel onboard video card. No luck again, though it crashes a bit later: inside KDM.

It's either broken KDM, or incorrect Nvidia downgrade. I've downgraded nvidia and nvidia-utils; have I forgotten something? Working now from an older Arch installation on a USB drive, afraid to upgrade.

Yes: you need to downgrade the kernel also, or you can switch to the legacy 340xx packages which work with the current kernel.

There seems to be no 340xx:

$ pacman -Ss nvidia
extra/libcl 1.1-4 [installed]
OpenCL library and ICD loader from NVIDIA
extra/libvdpau 0.8-1 [installed]
Nvidia VDPAU library
extra/nvidia 340.32-2 [installed]
NVIDIA drivers for linux
extra/nvidia-304xx 304.123-6
NVIDIA drivers for linux, 304xx legacy branch
extra/nvidia-304xx-libgl 304.123-1
NVIDIA drivers libraries symlinks, 304xx legacy branch
extra/nvidia-304xx-lts 304.123-3
NVIDIA drivers for linux-lts, 304xx legacy branch
extra/nvidia-304xx-utils 304.123-1
NVIDIA drivers utilities and libraries, 304xx legacy branch
extra/nvidia-libgl 340.32-1 [installed]
NVIDIA drivers libraries symlinks
extra/nvidia-lts 340.32-3
NVIDIA drivers for linux-lts
extra/nvidia-utils 340.32-1 [installed]

Do you mean 304xx, or lts, maybe; what kernel exactly?

NB The quoted console output belongs to the backup system (USB drive; kernel 3.16.3-1)

UPD:

Sorry, forgot about pacman -Sy .
Yes, it's just

# pacman -Sy
# pacman -S nvidia-340xx nvidia-340xx-utils
# pacman -Su

Should have RTFM first.
