Graphics in VCV Rack (linux) different [SOLVED]

VCV Rack
1

Hi!

I am running VCVRack on Ubuntu 18.04 and experience some strange behaviour with the graphics in VCVR 0.6.2c.

When I start Rack by double clicking app it starts fine and looks good

But when starting Rack from a .desktop the graphics are less good.

What is happening?

What’s your graphics card and installed graphics drivers?

I found this after some googling and running in terminal - dont know if it helps…

Grafik: Intel® Ivybridge Mobile
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
Vendor: Intel Open Source Technology Center (0x8086)
OpenGL vendor string: Intel Open Source Technology Center

Intel HD3000 is pretty old. I haven’t tested Rack on that GPU. Perhaps time for a new laptop?

Rack is running good on it - its just when I start program from a .desktop file the graphics is
bad. When I click direct on app it works good - no need for a new laptop.

You need to cd to Rack’s directory before running it so it can load the assets. My wrapper for Rack does

#!/bin/sh
cd /path/to/Rack
./Rack

to avoid the issue.

From Installing & Running - VCV Rack Manual

with the command-line, cd into the Rack directory and run ./Rack .

You need to run Rack from the Rack directory. If you want to hack your own .desktop file, you need to use something like

Exec=bash -c 'cd ~/Applications/Rack && ./Rack'

Ok, thanks korfuri!

But how to place this into a .desktop-file?

Or…should I make a .sh and point .desktop to that file instead, hmmm will test this chain.

Ok Andrew - will look at it. Thanks.

Andrew and korfuri - a big thanks to both of you!

Both solutions worked well!

In linux you place a desktop file in your ~/.local/share/applications folder. In this location it will then show up in your Menus setting. No need for a shell script.

PS. Full desktop file specs from freedesktop.org are here

My .desktop file that seems to work fine as an example:

[Desktop Entry]
Exec=/home/user/Applications/Rack/Rack
Icon=/home/user/Applications/Rack/res/icon.png
Name=VCV Rack MT
Path=/home/user/Applications/Rack
Type=Application

Setting Path is enough to set the working directory for this.

Wasn’t aware of Path. Your version is better then.
