comment Why don't my lightdm.conf edits affect my desktop screen resolution?
Editing the files under /usr/share/lightdm/lightdm.conf.d/ is the wrong way of changing lightdm.conf. The LightDM project page says that system admins can override the default configuration in /etc/lightdm/lightdm.conf.d/ or /etc/lightdm/lightdm.conf You shouldn't edit files under /usr/share/lightdm/ because while it might work for a while it's liable to get overwritten by package updates Source: LightDM project page freedesktop.org/wiki/Software/LightDM Please correct your answer

comment Ubuntu on Lenovo Yoga 2 Pro
My answer on the other page was deleted by a moderator apparently (sometimes stackexchange's policies make no sense), but I wrote the same thing as here - to upgrade linux-firmware and use the fixed ideapad_laptop module. It's frustrating that it doesn't fully solve the problem, but in my case I think it's made an improvement.

The question you linked to in the comment above: askubuntu.com/q/517463 I just had the first wifi problem in the 2 days since I updated linux-firmware, so looks like it wasn't a full fix unfortunately. But I just had to wait a couple of minutes and then reconnect, no reboot needed. Not sure why your symptoms would be different.

I've added a comment to that other question. The symptoms I got with the wifi was that every 30 mins or so it'd lose connection and NetworkManager would prompt for the password. Usually needed to disconnected, wait a minute or 2 and then reconnect before it'd work. After installing the new linux-firmware package this didn't happen. Note that I also have the fixed ideapad_laptop module (as detailed above). Possibly it's the combination of those 2 things that solved it (so far) for me.

@rubo77 I found that upgrading the linux-firmware package to at least version 1.134 fixed the wireless card instabilities, at least so far. See further down this page I've posted the full details.

comment How can I ensure transmission traffic uses a VPN?
Warning: this doesn't work with Deluge, AFAICT because Deluge spawns off sup processes. I've tested it carefully and my setup is right - sudo -g vpnroute ping google.com will show 'Destination unreachable' until I enable the VPN on tun0. But the Deluge UI can always download torrents, whether VPN is connected or not. With pgrep -G vpnroute I found it's because only the initial /usr/bin/python process is run under the vpnroute GID, spawned deluge-gtk processes seem not to be.

comment Install a list of packages only if they aren't already installed
Further to the above this works on rpm-based systems with rpm -q, it simply looks in the local db of installed packages and is very quick, and importantly doesn't need to time out in case there is no network.

comment Install a list of packages only if they aren't already installed
I guess I could. The reason I didn't consider it first-off is I use this as part of an automated script that does all my configuration (all config files, network setup etc.). That means whenever I change anything at all I need to re-run this script on two separate machines so wanted it to run in as short a time as possible. Running apt-get, especially on the laptop which might not always have an internet connection, is quite heavy-weight in terms of the time it takes.
