just with the option acpi_backlight=vendor which is needed if i want to toggle brightness When I reported the problem I have been advised to create a bug report to make sure the "possible quirks made to make work the brightness" are integrated upstream, so that we can then refocus on the sleep/resume crash so the timeline is: - - I report the crash/resume bug and get redirected to creating a video bug instead - - I report the video bug and get redirected to sending the information to involved people/dev because it's an upstream bug - - I report the problem here and I'm advised to use "acpi_backlight=vendor" to fix the problem so I'm a bit confused about what I should do now :-) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) Comment: Using GnuPG with Thunderbird -
