Public bug reported: HP ProBook 4740s, new installation of Ubuntu
lsb_release -rd Description: Ubuntu 14.10 Release: 14.10 Linux HP 3.16.0-25-generic #33-Ubuntu SMP Tue Nov 4 12:06:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux xserver-xorg-video-intel: Installed: 2:2.99.914-1~exp1ubuntu4.1 Candidate: 2:2.99.914-1~exp1ubuntu4.1 lshw -c video *-display description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:48 memory:c0000000-c03fffff memory:b0000000-bfffffff ioport:3000(size=64) Suspend by menu at right upper corner. Waits... Wake up by button. Wallpaper and logon screen is appeared, periodically I can login and begin work, but not more than 5 seconds and system completely freezed. I can stay at login screen without keypress and its freezed too after some seconds. No mouse, keyboard, led or ssh activity is allowed. Kernel dead. Using fglrx or fglrx-updates it's no problem with suspend and resume, while using discrete card (not workaround for me). I disabled Radeon card (in BIOS) and using i915. All fglrx and fglrx- updates is completely removed, xorg-radeon too. kernel option i915.modeset=0 resumed without hangs (but with black screen), and nomodeset too. tried to create xorg.conf with uxa Section "ServerLayout" Identifier "layout" Screen 0 "screen" 0 0 EndSection Section "Device" Identifier "intel" Driver "intel" Option "AccelMethod" "uxa" BusID "PCI:0@0:2:0" EndSection Section "Monitor" Identifier "monitor" Option "VendorName" "HP" Option "ModelName" "HP Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "screen" Device "intel" Monitor "monitor" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection but hangs too :( Hibernation works without any problem. Tried latest Linux Mint (booting with usb-stick) - hangs on suspend/resume too. Sometimes ago can suspend/resume at Windows 7, but I hate this OS. I suffered to resolve this problem last three days... ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1397277 Title: Kernel dead after suspend/resume at i915 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1397277/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
