Full Changelog: https://github.com/hertg/egpu-switcher/compare/0.18.2...0.19.0

🐞 Fixes

• Updated dependencies for good measure

Note This theoretically fixes CVE-2022-32149, please note that egpu-switcher was not affected by this DoS vulnerability as it neither interacts with the network, nor does it parse any HTTP Accept-Language headers.

🐞 Fixes

• Fix issue with PCI devices that are connected on a >16bit PCI domain (#91)

✨ What's changed

The whole script has been rewritten in golang (#85) to allow for easier maintainability than the previous bash script. Not only has egpu-switcher been rewritten, but also some internal concept changes were made and additional features have been added.

💥 Breaking Changes

• The config file format has changed in a non backwards-compatible way and it can't be migrated automatically. Please re-run egpu-switcher config if you are updating from an earlier version.
• The egpu-switcher remove command has been dropped for now.

🎉 Features

• The detection interval and timeout can now be configured in the configuration file (#79)
• Allow switch hook scripts to be configured (#73)

🐞 Fixes

• GPUs are now identified by Vendor/Product instead of the PCI Id they were assigned (#48)
• GPUs on non-zero PCI domains are working now (#69)
• The graphics driver used is now directly taken from what sysfs reports instead of the buggy driver assumptions made in the old script (#81)

📓 Technical Changes

• The X.org config is now in /etc/X11/xorg.conf.d/99-egpu-switcher.conf instead of /etc/X11/xorg.conf (#72)
• Additionally to the egpu-switcher-git AUR package, more stable alternatives pointing to the latest release are now available: egpu-switcher and egpu-switcher-bin
• Requirements for bash and pciutils have been dropped

Fixes

• Fix some timing issues: if egpu is not connected on bootup, probe again every 500ms and give up after a few seconds instead of immediately (PR #52)
• Fix "unbound variable" error when trying to switch to disconnected egpu (PR #53)
• Remove previously installed egpu-switcher manpages on "make install" to prevent unnecessary user prompt (PR #54)
• Fix issue in "if" statement when a user has customized their "Driver" part in xorg.conf.egpu (PR #57)

Fixes

• egpu-switcher no longer recognizes non-graphics devices as an eGPU (#49, thanks to @toumorokoshi)
  This fixes a problem where devices like Thunderbolt Docks were recognized as the eGPU if they get connected to the same PCI Bus.

Features

• Add egpu-switcher remove method to remove eGPU without a reboot (experimental) (see PR #44, thanks to @ewagner12)
• Updated manpages

Fixes

• Update systemd-service, hopefully fixing some timing issues on bootup
  • Changed WantedBy=multi-user.target to WantedBy=graphical.target
  • Add After=bolt.service
• Remove artificial delay from switch method

No Code Changes

• This release has no code changes since 0.13.1, the version had to be increased due to a publishing error on launchpad

Fixes

• Fix bug in display detection which prevented to switch to the eGPU with AMD cards (thanks to ewagner12 for the fix) (closes #34, closes #38)
• Add "not recommended" hint to the "define a specific internal GPU" setup step

Fixes

• Prevent error on cleanup if setup hasn't been executed (see #25)
• Remove unnecessary console print that may confuse users (see #29)

Features

• Better GPU detection with lspci -d (see #23)

Fixes

• Prevent error on egpu-switcher clean command (see #24)

Breaking changes

• Removal of nvidia-xconfig method for detection of GPUs. lspci is now used everywhere as it works for NVIDIA and AMD GPUs (see #18).
  This only affects you if you explicitely use it in one of your own scripts, lspci was already the default option for all methods.

Features

• It's no longer required to specify the internal GPU (but still possible), because that caused trouble in some situations. It's overall preferred to let X-Server figure it out themselves what GPU to use, if no EGPU is connected. (see #9)
• Save the user configuration (internal/external GPU) to a config-file at /etc/egpu-switcher/egpu-switcher.conf. This prevents the need to re-run the setup after every upgrade in the future. (see #5)
• Introduction of the egpu-switcher config command to reconfigure which GPUs to use (This is needed because the setup command does no longer prompt the user if a configuration already exists).
• Added manpages: man egpu-switcher finally returns something :)

Fixes

• Changed egpu.service from Type=Simple to Type=oneshot as it fits better for its purpose. (see #16)
• Refactored a lot of code in order to conform to bash scripting best-practices
• Updated README

Do not install this version, the build failed because of a small error. Use 0.11.1 instead.
