The thing is I am really afraid of upgrading the BIOS just to give it a shot because of this:
"Just update XPS 9575 Bios on the week of Sept 9, now the laptop is totally unresponsive, not able to power on, totally black screen, no light comes on, fans won't kick on, no Dell logo shows. Tried many ways, many times to enter the bios recovery mode suggested by Dell and other websites, but nothing works. The computer is dead now. Very, very frustrated." ### Apparently the track pad issue affects Windows as well: "I'm a Dell xps 9575 user running windows 10 fam 64. I can report that the track pads works absolutely inconsistantly: Mouse icon gets immobile at random moments wich is accompanied by unresponsible click. I'm running on bios 1.7.1 since one hour with no change compared to 1.5.1 and the previous bios didn't work either. I wish I could install ubuntu mate but the laptop belongs to my son. Windows update, intel driver and dell driver detects no upgrade to be done. The frozen trackpad issue seem to come from excessive chest pressure that bends the bottom of the trackpad and it also seems that the mouse gets back to life when bending the other way:both thumbs under track pad with fingers under palmrests..." ### Does anyone have an "effective" workaround at the moment (and with which BIOS?), like pointed out earlier here?: "This is still a problem on the newly released 1.6.1 BIOS. Workaround for all versions with this issue - hit FN+END to enter sleep (or close the lid, by default this will enter sleep mode), then wake it back up. Input will work properly after that." ### All comments from: https://www.notebookchat.com/index.php/topic,96952.0.html?language =english-utf8 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1822394 Title: [Dell BIOSes dated 27 Mar 2019, XPS 9575, Precision 5530 2-in-1] laptop keyboard & touchpad not working at gdm screen after boot Status in libinput package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: On a dell XPS 15 2-in-1 with the latest 1.4.0 bios, my touchpad and keyboard are unresponsive at the gdm login screen. Keyboard works to unlock encrypted harddrive before that though. If I plug in a USB keyboard or activate my bluetooth mouse, I can use those to log in, and then after logging in the laptop touchpad and keyboard work again. Logging out of the desktop results in the laptop touchpad and keyboard working on the gdm screen. Did not see this behavior before upgrading from 1.2.0 bios to 1.4.0 bios, but also had not rebooted in a while, so not sure if bios or package upgrades triggered this behavior.
