I should add that I use Dell's drivers for the Dock, maybe this is the cause ? Link to the driver https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=p20vd&oscode=wt64a&productcode=dell-wd19dc-dock I have Version 01.00.14.01, A03 of 22 May 2020. I gave the wrong link for the driver, this is the correct one : https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=cwcf9&oscode=ubt18&productcode=dell-wd19dc-dock And acknowledge that there is also a Dell BIOS on my computer : https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=80fmt&oscode=ubt18&productcode=precision-15-7540-laptop Which I updated to version 1.9.0 (In reply to Matthias from comment #1) > I should add that I use Dell's drivers for the Dock, maybe this is the cause > ? > TBH, I don't know. In this kernel bugzilla, we only focus on problems with vanilla kernel, which means that no out of tree driver should be used. Bug closed. Please feel free to reopen it if the dual screen still works with vanilla kernel, and the problem can still be reproduced. |
