# Notes:
|
|
|
|
# - For IPTS, see
|
|
|
|
# > https://github.com/jakeday/linux-surface/issues/544#issuecomment-519126757
|
|
|
|
# for an explanation/discussion. We do not unload/reload modules for now as
|
|
|
|
# the IPTS drivers should be able to resume/suspend without this. If you
|
|
|
|
# experience any issues on suspend/resume, please file an appropriate issue or
|
|
|
|
# join the discussion linked above so that we can fix it. As a temporary
|
|
|
|
# workaround, you may want to uncomment the IPTS-related lines above.
