I have some probleme using xrandr.
I have a laptop on CentOS 6.3, and the resolution is 1600*900. I want to increase the resolution to have 1600*1000 because some soft I have to run on it can not ajust their size.
Therefore I created a new size of virtual screen 1900*1000 with
$ cvt 1900 1000
And then :
$ xrandr --newmode [...]
$ xrandr --addmode[...]
My problem is : the new resolution is created but when I use it, I have a part invisible and not accesible (100 pix) and I can not move the screen by "pushing" the end of the screen with the cursor.
How can I set up this last part ?
Thanks
I found a way to do what I was looking for.
in a terminal :
xrandr --fb 1600x1000 --output LVDS --mode 1600x900 --panning 1600x1000
I saw it on this page :

I am working on the custom build Yocto Linux running on Wayland, but I do not know how to flip the screen horizontally, as I don't see xrandr in it (I did find xorg.conf). Can someone help on this? Thanks
Wayland does not use X server see this graphic
Wayland and its clients use EGL to draw directly into the framebuffer. It can be a foundation for on overlaying X but it does not have to.
For Wayland Weston there is a solution in https://community.nxp.com/t5/i-MX-Processors/How-can-I-rotate-Wayland-weston/m-p/695720 :
I found the device name at "/var/log/weston.log". And I add these
lines to "/etc/xdg/weston/weston.ini" :
(My default screen size :1024x768 and 60Hz)
[output]
name=fbdev
mode=768x1024#60
transform=270
You can set "transform" 90 or 270 to use your display vertical.
Weston is also intended to replace X on embedded systems (https://en.wikipedia.org/wiki/Wayland_(display_server_protocol)) :

I am using VMware fusion on my mac. I would like to change the res to 1600 x 900 in windows 10 but the options does not seem to be there.
Any assistance is greatly appreciated. thanks
I am using multiple monitors so within display settings on my mac, I change the display to 1600x900 to the left monitor. I then went to my VM settings and under 'Virtual Machine Resolution' set the full screen option to 'stretch the vm in the screen'. Set the vm to full screen within that left monitor and then go check in windows what the resolution is, it is now 1600x900!

I installed Ubuntu 16.04 yesterday and since then I have a problem with the mouse cursor.
It starts randomly disappearing and flickering a lot mostly when you try to close the window.
I have searched for a solution on Google and here but didn't find anything.
I had the same problem some time back when using ubuntu 14 version. You can fix it manually by going to Open System Settings > Displays. In the Displays window, you will see an Unknown monitor. Click it and disable it.
If you have 2 built in display in red and green color.. Disabling the green built in display will solve the issue.

When giving a talk I usually use two screens: One is the wall showing the presentation to the audience, the other one is my Laptop screen with a mirror of the presentation, my speakernotes etc.
During the talks I pretty often do demos using a terminal. This requires that
I turn around to check at the wall if everything works correctly. To avoid this I would like to have two terminal window, one on my laptop screen where I am typing and a mirror of it which is shown to the audience at the second screen. How can I do this?
Take a look to the screen program. It does perfectly what you are trying to do. The following link gives a simple example of screen usage:
Start a new screen session with session name:
screen -S <name>
list running sessions/screens:
screen -ls
Attach to a running session:
screen -x
Attach to a running session with name:
screen -r session_name

So I am using Linux mint and I have a 4k monitor so my cursor size is very very small. I have tried increasing it through Preferences->general and this worked but it is still very very small. Can this be increased through linux terminal?
Try the following where XX is the custom size entered as an integer.
gsettings set org.cinnamon.desktop.interface cursor-size XX
The default small one should be something like 24.
If anyone here wants to reduce beyond min size then use a negative number in place os XX in above command
