4.8-rc6 does not resolve this issue. Neither did the Oibaf driver PPA, or the AMD Catalyst drivers for 16.04.
I have to question this process of just blindly testing the next RC each time one comes out. This problem is related to the 8700P AMD processor (and similar AMD chipsets) and/or the decision to disable the nomodeset kernel option despite it being a long-term workaround for both AMD and Nvidia graphics problems. Unless there is explicit development to address these issues, trying new RCs in the hopes that the issues have been accidentally resolved is a waste of my time, your time as an Ubuntu maintainer, and the time of all the other individuals that have reported similar issues. Is the Linux community really incapable of effectively communicating (or tracking) work on issues reported inside one distro that relate to upstream issues? As a software QA professional, I have to say that this entire process has been disillusioning. I purchased this laptop over a year ago to give myself a dedicated development machine, but this is the second bug I've encountered that makes the machine effectively useless. Worse, this issue is a regression, since the chipset worked just fine with the graphics drivers available in 14.04 through 15. I recognize that sometimes hardware gets left behind by new development, but this is not an old chip. I really want Linux and Ubuntu to be an effective desktop environment. But between poor communication and decisions like removing fglrx and nomodeset that make modern, current hardware *less* effective than it was on older versions, it doesn't seem to be there yet. I'm currently experimenting with using Windows and the Ubuntu bash subsystem as a development environment, and if that proves effective (or at least slightly productive) I'll likely be removing the Ubuntu partition. Until I do that, I'll try to update this once a month or so. -- 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/1596216 Title: Black screen on boot; no modeset workaround broken by 16.04 Status in linux package in Ubuntu: Expired Bug description: This bug appears to occur in several distros and architectures. On this machine, it appeared somewhere in the last week of January, 2016, after a system update. On boot, the laptop monitor often flickers several times (signal connecting and disconnecting) and always settles onto a full backlight back screen. The screen does not change after that. I found reports that adding nomodeset to the grub parameters would resolve the issue. It does, but the workaround has significant issues in 16.04. The nomodeset parameters conflict with both the amdgpu driver package and the radeon driver package. When the machine boots, it is in 800x600 resolution. While I can add new resolutions, attempting to switch to them with xrandr throws the error "configure crtc0 failed" ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-24-generic 4.4.0-24.43 ProcVersionSignature: Ubuntu 4.4.0-24.43-generic 4.4.10 Uname: Linux 4.4.0-24-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: jbhelfrich 2053 F.... pulseaudio /dev/snd/controlC0: jbhelfrich 2053 F.... pulseaudio CurrentDesktop: MATE Date: Sat Jun 25 14:49:22 2016 HibernationDevice: RESUME=UUID=51835e9e-6087-4108-af31-95e11fc3401c InstallationDate: Installed on 2015-10-30 (238 days ago) InstallationMedia: Ubuntu-MATE 15.04 "Vivid Vervet" - Release amd64 (20150422.1) MachineType: HP HP Pavilion Notebook ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-24-generic.efi.signed root=UUID=613f6223-b665-4289-9dfa-7b003124dfdf ro quiet splash nomodeset i8042.dumbkbd=1 vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-4.4.0-24-generic N/A linux-backports-modules-4.4.0-24-generic N/A linux-firmware 1.157.1 SourcePackage: linux UpgradeStatus: Upgraded to xenial on 2016-06-24 (1 days ago) dmi.bios.date: 08/06/2015 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: F.13 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 80AF dmi.board.vendor: HP dmi.board.version: 81.28 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrF.13:bd08/06/2015:svnHP:pnHPPavilionNotebook:pvr:rvnHP:rn80AF:rvr81.28:cvnHP:ct10:cvrChassisVersion: dmi.product.name: HP Pavilion Notebook dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1596216/+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
