Chrome Remote Desktop
The remote desktop session has to be headless :(
- Install the deb (can convert with alien & co)
- Patch with modern_distro.diff (cherry-pick what your system needs)
- To support automatic desktop resizing:
- Works with any window manager
- Build Xvfb with xvfb-randr.diff
- Expose as /usr/bin/Xvfb-randr
- If replacing system-wide binary by repackaging, simply
# ln -sf Xvfb /usr/bin/Xvfb-randr
