White background on login screen, plus crashes AFTER login

[Ygarl]

Hello all,

As you can see in the attached photo, I am having a very strange issue with being unable to see what I'm typing on login.
More annoyingly, when I DO login, it instantly crashes.

I am running Ubuntu Mate 16.04 64-bit, with an Nvidia 550ti graphics card.
I have been playing Regnum for years on this setup, and only re-installed after put a new SSD onboard. It's the first time I've run Regnum 64-bit though...

On crashing, I'm getting Segfaults every time, with an occasional:

*** Error in `./rolauncher': free(): invalid pointer: 0x00007ff2350ffd88 ***
Aborted (core dumped)

Or for spice, the same thing with an occasional:

*** Error in `./rolauncher': munmap_chunk(): invalid pointer: 0x0000000002c9f5b0 ***
Aborted (core dumped)

instead, for spice.

I've actually never had a problem running Regnum I couldn't figure out before since literally 2008 so this is a bit of a mystery to me.
I'd like to not have to use my Windows 10 partition <Ptui! Damn you, Elite Dangerous!>

Ta,
Bob

Rolauncher seems to have serious issues with some themes.

Try the Adwaita theme, that one works for me. I switch it in just for the launcher and reset it afterwards.

As enio tell RO launcher client for linux have not been updated for age now.

To workaround they are this script file to put at the root of the game:

cat <'EOF'>$ start.sh 
#!/usr/bin/env bash

declare gtkrc_dir="${HOME}/.themes/Adwaita/gtk-2.0/"
declare gtkrc_ori="${gtkrc_dir}/gtkrc"
declare gtkrc_new="${gtkrc_dir}/gtkrc_"
declare -i pid=0

if [[ ! -e "${gtkrc_dir}" ]]; then
    mkdir -p "${gtkrc_dir}"
fi

if [[ ! -e "${gtkrc_new}" ]]; then
    echo "# dummy" > "${gtkrc_new}"
fi

if [[ -e "${gtkrc_ori}" ]]; then
  mv "${gtkrc_ori}" "${gtkrc_ori}".bak
fi

cp "${gtkrc_new}" "${gtkrc_ori}"

${PWD}/rolauncher &
pid=$!

wait $pid
mv "${gtkrc_ori}".bak "${gtkrc_ori}"
EOF

$ chmod +x ./start.sh
$ ./start.sh
