[Bug 1742602] Re: Blank screen when starting X after upgrading from 4.10 to 4.13.0-26
The blank screen problem is still present in my case on Ubuntu 18.04 using a Dell 5570 machine. Upgrading to kernel 4.17.2-041702 has solved the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742602 Title: Blank screen when starting X after upgrading from 4.10 to 4.13.0-26 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1742602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1510344] Re: Keyboard Backlight Turns on at boot
On Dell E5570, gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower/KbdBacklight --method org.freedesktop.UPower.KbdBacklight.GetBrightness works well, returns 0, 1, or 2, depending on keyboard backlight level OFF, DIM, FULL. But gdbus call --system --dest org.freedesktop.UPower --object-path /org/freedesktop/UPower/KbdBacklight --method org.freedesktop.UPower.KbdBacklight.SetBrightness i switches backlight to full power independently of parameter i. Even backlight timeout is deactivated: backlight just does not switch off. This deactivated timeout "setting" made by Ubuntu is persisted. Even if I reboot into DOS or BIOS setup, backlight just stays on. I have to setup the timeout vale in BIOS again to activate the timeout function.

I am adding Dell E5570. Backlight turns on at boot and does not switch off ever. Ubuntu 16.04 with unity-settings-daemon version 15.04.1+16.04.20160209-0ubuntu2.

[Bug 1071699] [NEW] [Dell Lattitude E6420] Boot fails
Public bug reported: Kubuntu 12.10 64bit fails booting on my Dell Lattitude E6420 notebook. Previous version 12.04.1 worked fine. After upgrade to 12.10 system no more boots. Kubuntu 12.10 64bit DVD does not boot, either, with same symptoms. When using the old kernel (3.2.0) and initramfs, system boots properly. Using the new kernel (3.5.0) splash screen shows, dots are moving in the logo. Then the logo stops moving and then system freezes, I am not able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.2.0 kernel. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1071699 Title: [Dell Lattitude E6420] Boot fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1071699/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
