When you try share screen or use screen recorder in Arch Linux or Manjaro, the screen is blinking like in here: https://imgur.com/7dzeiXr
How to solve?
If you use x11, then to solve this problem :
Uninstall package: xf86-video-intel
Remove file (if it exists): /etc/X11/xorg.conf.d/20-intel.conf
Reboot your system
Try your screencast again...

I am testing Parrot OS and would like to put it in full screen mode in Hyper-V
Tried seeking through parrotsec documentations but couldn't find any reference.
Found a solution.
Since Parrot OS is using Debian, I just tried to modify the Grub Setting by adding video=hyperv_fb:1440x900
nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=hyperv_fb:1440x900"
CTRL x + Y + Enter
sudo update-grub
sudo reboot
Then works as expected now. Thanks!
Another option I found is to enable enhanced session mode on Hyper V. On host run in powershell:
Set-VM "YourVMName" -EnhancedSessionTransportType HVSocket
On guest parrot os I used this script:
https://raw.githubusercontent.com/mimura1133/linux-vm-tools/master/kali/2021.x/install.sh
Bonus is clipboard between host and guest also works after this.
When I type on my keyboard ctrl+alt+T or ctrl+alt+F1,2,3 and so on nothing happens.
I have raspbian Buster lite. And I've estblished raspberry to kiosk mode by adding chromium to /etc/xdg/openbox/autostart
Where should I see to find something that doesn't allow to go to terminal?
I found my mistake. In the file /boot/cmdline.txt was fbcon=map:2 when I removed it, everything became OK
I try to build a reproducible automated build environment based on Debian 8.1 Jessie.
I created a boot iso image based on a netinstall image and put a preseed.cfg file in int for automatic installation.
I managed to get it bootable with BIOS and UEFI and can install a KDE Developer Debian in VMWare Workstation 11 fully automated.
I have also a server iso image to install a debian Server with Jenkins, both with BIOS and UEFI Boot.
But after the installation, the Version with UEFI Boot shows a black Screen when started.
I can blindly log in, start the gui with "startx" and see my installed xfce desktop. When i quit xfce the console is usable and visible.
I tried suggested bootparameters "nomodeset" and "vga=Linux" that i found with google to no avail.
I also tried to debug the boot prozess, to find out which command leads to a blank screen, but i did not find the right place to delay the processes at bootup so i can see when the messages dissapear (quiet bootparameter was removed :-)
I also tried to reset the console to no avail.
Can anybode point me to a tool that does the same "switching" like X so the console is useable?
Can anybody give me some hints how to debug the bootprocess to find out which command is causing this behaviour?
I dont want to install X because this should be a headless server system later.
I managed to get my system to boot using the kernel command line modprobe.blacklist=vmwgfx, or placing 'blacklist vmwgfx' in /etc/modprobe.d/*.conf
I assume it is some bug in the vmwgfx module, however as this workaround works for me I have no immediate need to investigate further.
I have set up some Raspberry Pi's in my corporation with Screenly inside. It has simple overlay to show a webpage with some slides.
My problem is the screensaver that turns on when I'm not at work. I tried to add a reboot command to the crontab, edit boot settings with screensaver, etc.
When testing it for few (6-8) hours, the screen never turns black, but overnight when I'm gone, the screen turns black. What can I do to stop this?
There was a similar question posted on the Raspberry Pi StackExchange.
There they suggest installing x11-xserver-utils (with apt-get install), and adding these lines to your ~/.xinitrc file:
xset s off # don't activate screensaver
xset -dpms # disable DPMS (Energy Star) features.
xset s noblank # don't blank the video device
Restart X, and your problem should be solved.
I have Ubuntu, version 12. I installed ATI driver and I'm getting an error running in low graphics mode.
I needed to install the driver because every time I update or upgrade Ubuntu, right after installing the packages the system runs in low graphics mode.
The answer here also couldn't help me.
Graphics card model: ATI Radeon HD 3600
Installing fglrx also didn't help. The ATI driver is still installed and it still runs in low graphics mode. What should I do?
First, you should understand that your graphics manager is messed up and that is what you want to fix. Now; here is a solution to your problem:
Here is a simple guide showing you how to do it step by step:
A step by step guide to fixing "your system is running on low graphics"
When you turn off your computer, reboot and hold these three keys:
CTRL + ALT + F1
This will open the terminal where you can enter commands that I am going to show you below:
sudo apt-get update
Next enter the following command:
sudo apt-get -d install --reinstall gdm
Next enter the following command:
sudo apt-get remove --purge gdm
Next enter the following:
sudo apt-get install gdm
Almost done; When asked to choose, please select GDM and then finally:
sudo reboot
That is all you need to solve this problem!
Ok. Let me try to help you :D
-Go to Recovery mode
-Enable network (so you have internet connection)
-Go to Root option (Recovery mode)
-When you are in terminal delete lightdm type without brackets {sudo apt-get remove --purge lightdm}
-Then type without brackets {sudo apt-get install lightdm} (wait to install it)
-Then type without brackets {sudo service lighdm start}
-When it's finished type exit (you will get back to Recovery console)
-Then go on third option dpkg (Repair broken packages)(confirm with Y)
-When it's finished with installing packages type without brackets {sudo reboot}
-After reboot you will have back your Ubuntu! :D
I solve this problem after 1 day... Im a new user :D
Almost forgot i have Ati Radeon HD6770 graphic card, if you have Nvidia try it... Hope this was helpful!
Another possible issue could be installing new programs in bin. I am not sure if that what is causing you the problem but I faced this issue because of the same issue. If I understand correctly, bin is supposed to contain only executables. By mistake I moved a whole big program to bin and when I restarted the system, I saw this error. A simple solution that I found is the following. Say you have moved the big folder ABC to bin.
Start terminal by typing Ctrl+Alt+F1 and login with your username and password.
Login to root by typing
sudo su
and providing password.
go to bin by typing
/usr/bin
type
ls -lrt
This last command will show all the files chronologically. See last few of them. One of those, say ABC, must be the one that moved by mistake to bin.
Remove that by typing
rm -r ABC
and then restart by
sudo reboot
And you get your graphics back!
You can try and turn off the switchable graphics in the BIOS:
after that, it will be possible to use the Intel video card only with proper drivers on Ubuntu.
Here is the source: http://thegeekyland.blogspot.com/2014/07/ubuntu-1404-lenovo-g510.html
In any ubuntu OS version 12.04,14.04 configured with the old graphic card ATI/RS690
change the setting as below
etc/default/grub/
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset "
sudo update-grub
Restart
