Qubes specific VM config files
|
|
==============================
|
|
|
|
Those files are placed in /rw, which survives VM restart, so can be
|
|
used to customize single VM (not all VMs based on the same template).
|
|
The scripts here all run as root.
|
|
|
|
- `/rw/config/rc.local` - script run at VM startup. Good place to
|
|
change some service settings, replace config files with its copy stored
|
|
in /rw/config etc. Example usage:
|
|
|
|
~~~
|
|
# Store bluetooth keys in /rw to keep them across VM restarts
|
|
rm -rf /var/lib/bluetooth
|
|
ln -s /rw/config/var-lib-bluetooth /var/lib/bluetooth
|
|
~~~
|
|
|
|
- `/rw/config/qubes-ip-change-hook` - script run in NetVM after
|
|
external IP change (or connection to the network)
|
|
|
|
- `/rw/config/qubes-firewall-user-script` - script run in ProxyVM
|
|
after each firewall update. Good place to write own custom firewall
|
|
rules
|
|
|
|
- `/rw/config/suspend-module-blacklist` - list of modules (one per
|
|
line) to be unloaded before system going to sleep. The file is used
|
|
only in VM with some PCI devices attached. Supposed to be used for
|
|
problematic device drivers.
|
|
|
|
Note that scripts need to be executable (chmod +x) to be used.
|
|
|
|
Also take a look at [bind-dirs][/doc/bind-dirs] for instruction how to easily
|
|
modify arbitrary system file in AppVM and have those changes persistent.

GUI and audio configuration in dom0
|
|
===================================
|
|
|
|
GUI configuration file `/etc/qubes/guid.conf` in one of few not managed
|
|
by qubes-prefs nor Qubes Manager tool. Sample config (included in
|
|
default installation):
|
|
|
|
~~~
|
|
# Sample configuration file for Qubes GUI daemon
|
|
# For syntax go http://www.hyperrealm.com/libconfig/libconfig_manual.html
|
|
|
|
global: {
|
|
# default values
|
|
#allow_fullscreen = false;
|
|
#allow_utf8_titles = false;
|
|
#secure_copy_sequence = "Ctrl-Shift-c";
|
|
#secure_paste_sequence = "Ctrl-Shift-v";
|
|
#windows_count_limit = 500;
|
|
#audio_low_latency = false;
|
|
};
|
|
|
|
# most of setting can be set per-VM basis
|
|
|
|
VM: {
|
|
work: {
|
|
#allow_utf8_titles = true;
|
|
};
|
|
video-vm: {
|
|
#allow_fullscreen = true;
|
|
};
|
|
};
|
|
~~~
|
|
|
|
Currently supported settings:
|
|
|
|
- `allow_fullscreen` - allow VM to request its windows to go
|
|
fullscreen (without any colorful frame). Regardless of this setting,
|
|
you can also set window fullscreen using trusted window manager
|
|
settings (right click on title bar).
|
|
|
|
- `allow_utf8_titles` - allow to use UTF-8 in window titles,
|
|
otherwise non-ASCII characters are replaced by underscore.
|
|
|
|
- `secure_copy_sequence` and `secure_paste_sequence` - key sequences
|
|
used to trigger secure copy and paste
|
|
|
|
- `windows_count_limit` - limit on concurrent windows count.
|
|
|
|
- `audio_low_latency` - force low-latency audio mode (about 40ms
|
|
compared to 200-500ms by default). Note that this will cause much
|
|
higher CPU usage in dom0.
