Status in linux package in Ubuntu: Incomplete Bug description: On my Asus EeePC 1015PED netbook, running Ubuntu 16.04LTS, I updated to kernel 4.4.0.145 on 3 April 2019. On the first boot after the update, I got the usual grub screen, then "Loading Linux 4.4.0.145 ... Loading initial ramdisk ..." then the screen went black with no mouse pointer or invite. I could hear disk activity ( & see the disk-activity light) then the usual drumroll for login, but the screen stayed black. I escaped using REISUO & retried several times with the same result. If I wait for the login drumroll then input my login, there is more disk activity (setting up the desktop) but the screen stays black. So the PC is not freezing, just no screen. Trying Ctrl+Alt+F1 (or other F keys) produces nothing. I can continue to use the PC normally if I select the previous kernel 4.4.0.142 at the grub screen. On 10 June 2019, I updated to kernel 4.4.0.150 & have the same black screen as with .145. So I am unable to use this PC AT ALL with current kernels. I asked about this problem on Ubuntu Forum https://ubuntuforums.org/showthread.php?t=2415972 with no success & the suggestion was to raise this bug... There may be useful information in that thread, including this output from "inxi -Fzr" (run in good kernel .142). chris@Netbk:~$ inxi -Fzr System: Host: Netbk Kernel: 4.4.0-142-generic x86_64 (64 bit) Desktop: Unity 7.4.5 Distro: Ubuntu 16.04 xenial Machine: System: ASUSTeK (portable) product: 1015PE v: x.x Mobo: ASUSTeK model: 1015PE v: x.xx Bios: American Megatrends v: 0801 date: 10/06/2010 CPU: Single core Intel Atom N455 (-HT-) cache: 512 KB clock speeds: max: 1667 MHz 1: 1667 MHz 2: 1667 MHz Graphics: Card: Intel Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller Display Server: X.Org 1.18.4 drivers: intel (unloaded: fbdev,vesa) Resolution: 1024x600@60.00hz GLX Renderer: Mesa DRI Intel Pineview M GLX Version: 1.4 Mesa 18.0.5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832863/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
