Solseek 0.12.0 has been released to Unstable
This is a minor release. Cleaned up the UI a little to resolve some issues when resizing the window and added a few more driver tools based on the Hardware section of Solus Help, including Broadcom, Open Razer, Piper, and Xbox.
Underneath this was removing cruft that was left behind during the development over the last few months to prepare for the 1.0 milestone. This release is essnetially the release candidate for that.
If there are any other drivers that you think are commonly used on Solus that are not in the tool, please let me know and I will add them. The list is based on the Solus Help, but I know there may be a few others.
In addition to Nvidia, below is the list of current drivers / tools that are in there...
