How to change the screen resolution when using RDesktop?

Question

How to change the screen resolution?

I tried with this command:

rdesktop <server_ip>

But the screen does not appear large.

Answer 1

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.

Answer 2

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>

Answer 3

This command gives you a full screen experience as well:

rdesktop -f

Answer 4

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

Answer 5

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.

Answer 6

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

Answer 7

Use the @DPI scaling option. Valid range is from 96 to 480 on Windows. Try @144 for 150% scaling, or @192 for 200% scaling.

For example:

rdesktop -g 90%@192 <server>

or

rdesktop -g 3000x1660@150 <server>

From the rdesktop man page:

-g <geometry>

Desktop geometry (WxH[@DPI][+X[+Y]]) ... The optional DPI parameter should be specified if the screen rdesktop is being displayed on is too far from 96 DPI for unscaled Windows to be readable. Windows currently accepts values from 96 to 480.

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