thanks for the help. I wasn't aware of that. Changing cables actually helped! Sorry for the noise

thanks for your help. You are right! Sorry for that.

This is strange, I know that my monitor can run 3440x1440 @ 60Hz... Any idea why this is not listed below? The monitor is connected via DP -> HDMI cable, but I don't see why this should be an issue?

Hi,

I have an AMD 5700XT installed and get surprisingly low frame rates ~30 FPS with glxgears. I know that this is not the right tool for benchmarking, anyhow, 30 FPS is well below the monitor refresh rate (I guess?).

# glxgears
Running synchronized to the vertical refresh. The framerate should ...

Hi,

I have a fresh gentoo install on my desktop PC and have some problems playing sound. I want to use the speakers of my monitor (connected via one of the hdmi ports of my graphic card) and my headphones which I use to plugin into the front. I followed the ALSA Gentoo Wiki: https://wiki.gentoo.org ...

I cannot remember that I explicitly build this kernel in recovery mode. This always appear (automatically?) when I add my kernel to grub. I guess this is some default behavior?

Thanks for your help. I disabled xdm and this indeed saves me from the black screen. But where to go from here? /sbin/udevd still stucks @100% CPU load...
What is the difference between my "normal" kernel and the kernel in recovery mode? Both of them are 4.14.83 kernels and I see no difference after ...

Hey,
I have the following problem with my laptop: when I try to boot my default kernel the boot process stops before I expect my login manager to show up and stucks with a black screen. From here on it is not possible to change to another tty, but I can still ssh into the machine. htop tells me ...

khayyam,

openrc+consolekit+shutdown issues started cropping up last year sometime, I don't know the cause or even all the ways the kits intertwine with shutdown, but most distros have swapped consolekit for elogind in the past year, so it was more of a blanket statement that users will generally ...

thanks for your comments

I checked my /var/log/messages but nothing suspicious here, except for this kworker dying (but this was 5min prior to the shutdown)

Hey guys,

I once again have a peculiar problem: my laptop dies on shutdown, that is: I type 'shutdown -h now' and after roughly one second the power is off, no LEDs are blinking, no friendly shutdown logs. I tried to figure out whether there are some correlation between my usage of programs or ...

may not be the fastest solution but solved the problem...

I accidentally ran pip freeze | xargs pip uninstall -y in the wrong console where the latter has root privileges and now there are some related problems as you may imagine. Is there anything like a requirements.txt that I can use to retrieve the system related pip installations?

Thank you for your ...

ok. Thank you for your help.

Hi,

I have some problems upgrading to texlive 2017:

[blocks B ] dev-texlive/texlive-genericextra
("dev-texlive/texlive-genericextra" is blocking
dev-texlive/texlive-plaingeneric-2017)

* Error: The above package list contains packages which cannot be
* installed at the same time on the same ...

I found the solution. One has to change the dest. 127.0.0.1:3022 to :3022. The reason for that is exactly what you said about the non-physical device lo.

Oh, you are right. So this behavior seems reasonable, but I still can't connect from another server. When trying to ssh into the VM (by using the IP of the host and default port 22), the connection does not establish,
$ ssh host_of_vm
ssh: connect to host ***.***.***.*** port 22: Connection timed ...

I want to ssh to my virtualbox via default port 22. In order to do so I already activated port forwarding of the virtualbox:

Host:3022 -> VM:22

such that ssh -p 3022 localhost works fine. Now I want to add another port forwarding using iptables to achieve:

Host:22 -> (forward) Host:3022 -> VM:22 ...

Great! Everything works! Thanks a lot.

Ok. Let me put it in another way: What modules do I have to activate for the intel graphics to work, that have to be deactivated for the nvidia card? At the moment it looks for me, that the intel graphics works with all modules disabled that also have to be disabled for nvidia? Currently I have ...

Thanks a lot for this in-depth howto. Just two more questions:

(1) At which stage do I have to append the VIDEO_CARDS variable with the respective NVIDIA keyword?

(2) What are the changes that I have to apply to my kernel config. The wiki entry https://wiki.gentoo.org/wiki/NVidia/nvidia-drivers is ...

Thanks both of you. x11-drivers/xf86-video-intel was indeed not installed, even though emerge -uDNav @world claimed to have 'nothing to do'. I installed the driver and now startx works as expected.

Ok. I like the latter approach. Could you elaborate this a bit more? (alternatively RTFMs with corresponding links are welcome, too;)

What do I have to activate in the kernel and what part do I have to set on blacklist? I guess the price of a framebuffer console that starts late during boot is fine ...

Ok. I removed all files from /etc/X11/xorg.conf.d/. Still startx fails.
Maybe it helps to mention, that I ran nvidia-xconfig during my attempts to use the nvidia card. I removed the generated file in /etc/X11/xorg.conf.d/ but I don't know if there are other remnants.

This is the new log:
