I have the same problem (not over heating but xorg now constant spinning). Prior to upgrade from 16.04 to 18.04 never had this issue. At first I thought it might be related to application but even when nothing is running the x server just spins.
A small detail - I actually have a 2500K but there was a regression in the xserver with 18.04 (16.04 worked fine but 18.04 cause a bug that existed in 14.04 (I think - i had this problem after 12.04 I think but it was a long time ago) to reoccur and the intel graphic would cause crashes) so I purchased a R72402364P - anyway an strace shows this small tidbit with the xserver spinning): (I filtered out other stuff the xserver is doing but as you can see from the timing it is spinning on ioctl calls): -- 1540153775.186129 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3f50) = 0 1540153775.186613 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.186650 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.186690 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186723 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186757 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186788 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186818 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.186849 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.186993 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.187389 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.187425 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.187460 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.187492 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 1540153775.187611 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.188095 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.188130 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.188264 ioctl(16, DRM_IOCTL_RADEON_GEM_WAIT_IDLE, 0x7ffd14ed46e0) = 0 1540153775.188579 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188605 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188628 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188652 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188675 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188698 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188721 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188744 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188768 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188793 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188816 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188840 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188863 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188904 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188930 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188953 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.188977 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189000 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189024 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189047 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189071 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189094 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189118 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed3df0) = 0 1540153775.189323 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed4150) = 0 1540153775.189363 ioctl(16, DRM_IOCTL_RADEON_GEM_BUSY, 0x7ffd14ed40f0) = 0 1540153775.189417 ioctl(16, DRM_IOCTL_RADEON_GEM_CREATE, 0x7ffd14ed45c0) = 0 1540153775.189451 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed45a0) = 0 1540153775.189487 ioctl(16, DRM_IOCTL_RADEON_GEM_VA, 0x7ffd14ed4650) = 0 1540153775.189518 ioctl(16, DRM_IOCTL_GEM_CLOSE, 0x7ffd14ed4648) = 0 ---- -- 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/1768976 Title: Ubuntu 18.04 is overheating after upgrade from 16.04 Status in linux package in Ubuntu: Confirmed Status in xserver-xorg-video-nouveau package in Ubuntu: Confirmed Bug description: Ubuntu is overheating at my laptop. Opening youtube on firefox is enough for critical temperature shutdown. Using lm-sensors for monitoring on 18.04 the temp varies between 70 and 85°C with only firefox or chrome open and doing nothing. On my old 16.04 with same using, the temp varies between 55 and 70°C. First thought was the driver nouveau is the problem, and finally I was able to install by add "nouveau.modeset=0" at livecd boot options, without temp shutdown. After install I disable the nouveau at modprobe blacklist, but the system continues overheating and shutdown with basic usage. I have no idea what's happening with the bionic at my laptop. My laptop is a Samsung RF411 i5 2nd Generation and Geforce 540M.
