How to change the screen resolution?

I tried with this command:

rdesktop <server_ip>

But the screen does not appear large.

  • FYI, using the -f option will use ALL the connected monitors...

I like using this command:

rdesktop -g 90% servername

Which will set the size of the remote desktop to 90% of the size of your local screen, which works quite well regardless of resolution.

    For dual screen: -g $(xrandr -q | awk '/Screen 0/ {print int($8/1.28) $9 int($10/1.2)}' | sed 's/,//g')

    Sorry, old thread. But when I work on a multiple monitor workstation I like that the remote desktop only in on one screen. I modified gacenkoa awesome script to this: -g $(xrandr -q | awk '/ connected / {print $4;exit}' | awk -F "x" '{print int($1/1.05)"x"int($2/1.1)}') This will look for the first connected monitor and then make the window a little smaller than that screen.

If you want to open the screen at a specific resolution, for example 1280×1024 resolution, add the -g flag:

rdesktop -g 1280x1024 <server_ip>

    Somehow I can make it as wide as I want, but the height is very limited. Dec 1, 2013 at 14:53

This command gives you a full screen experience as well:

rdesktop -f

    Doesn't work well with multiple displays: it spreads the window over all of them. Feb 3, 2016 at 16:37

    Ctrl + Alt + Enter if you're wondering how to minimise / exit the remote session

I found the answer to my question.

  • -k de: set keyboard layout
  • -g 1500x1150: set resolution of the rdesktop window
  • -r disk:mydisk=/home/soma: share your home directory with the remote machine

The full command should be:

rdesktop -k de -g 1500x1150 -r disk:mydisk=/home/soma 

I'd suggest that you consider a graphical tool such as Remmina (used to be called GRDC), which is available in the repositories.

sudo apt-get install remmina remmina-plugin-rdp remmina-plugin-vnc

It features easy to use drop downs and sliders for remote screen resolution, supporting multiple monitors and more.

It also supports VNC and SSH tunnelling, making it a one-stop-shop for all your most likely remote desktop connection needs. Finally, a handy gnome-panel applet makes connecting to your remote desktops a simple point and click experience.

    remmina-gnome doesn't exist (at least in Oneiric), but this worked for me: sudo apt-get install remmina remmina-plugin-rdp remmina-plugin-vnc

  • Nice one - they must have updated the packages in Oneiric. Have updated my answer.

I had the problem on my Ubuntu 20.10 notebook that my screen has 1920x1080 but only 14 inch, so the dpi is higher on my notebook screen than on the monitor of the remote computer

I could adjust this by using -g parameter with the DPI option, that is specified via an @ sign.

rdesktop -g 100%@150 <remote_computer>

The 100% refer to my screen size and the higher the value after the 1

  • thanks (from 2021).

I think Ctrl + Alt + KP+ also cycles through some available resolutions.

    That's for the local display resolution. He's using rdesktop which used RDP to pull a display from a remote Windows system. It's the resolution of thew Windows system displayed on his workstation he wants to adjust.
