[Ubuntu-x-swat] [Bug 1573959] Re: On-screen text disappears after suspend
I was affected by this issue in 16.04 with kernel 4.4 but it seems to have gone away since upgrading to 4.8; it's hard to tell because it is apparently impossible to reproduce on demand, and only happened maybe 1 in 10 times for me after resuming from suspend. @kyordhel: I am not sure that specific package is enough to fully install kernel 4.8; you should try installing the linux-generic- hwe-16.04 package which will give you the latest 4.8 kernel plus all necessary dependencies - for example if you did not install linux-image- extra-4.8.0-29-generic you may well be missing some modules that are required for decent desktop performance. -- 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/1573959 Title: On-screen text disappears after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1573959/+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
[Ubuntu-x-swat] [Bug 1663989] Re: Screen flickering
Confirmed that the bug is fixed in the 4.10 kernel series. Further confirmed that this is down to the i915.enable_psr parameter: Linux 4.8 with no command line => flickering (enable_psr defaults to on) Linux 4.8 with i915.enable_psr=0 => no flickering Linux 4.10 with no command line => no flickering (enable_psr defaults to off) Linux 4.10 with i915.enable_psr=1 => flickering ** Package changed: nvidia-graphics-drivers (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1663989 Title: Screen flickering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663989/+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

Sorry I should have explained better, I also have a Lenovo Edge E540 which is how I initially found this bug report via Google, but mine does not have the nvidia chipset, only Intel, so I didn't see how this could be caused by the nvidia driver.

[Ubuntu-x-swat] [Bug 1637316] Re: Screen flickering/tearing on Ubuntu 16.10 64-bit on kernel version 4.8.0-26-generic
Does adding "i915.enable_psr=0" to the kernel parameter line fix the issue?

Same issue, although I only have Intel graphics. Adding i915.enable_psr=0 to the kernel parameter line fixed the flickering for me.

[Ubuntu-x-swat] [Bug 1173492] Re: XRandR cannot set "scaling mode"
In my case the root cause of this issue was corrupted firmware rather than problems with XRandR (X11-xserver-utils). The machine in question had been running lm sensors 3.3.2 which was discovered to potentially cause firmware corruption in Sept 2013. The issue was immediately resolved following a re-flash of the BIOS on the T60 in question. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/1173492 Title: XRandR cannot set "scaling mode" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1173492/+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
[Ubuntu-x-swat] [Bug 1173492] Re: XRandR cannot set "scaling mode"
I'm using Intel integrated graphics instead of ATI/AMD, and I'm also on a 32-bit kernel instead of AMD64. I'm not sure if this points to separate driver issues, or an issue with X. I've also noticed that the issue seems to affect only the Thinkpad LCD (LVDS1), a monitor connected to VGA1 scales properly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/1173492 Title: XRandR cannot set "scaling mode" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1173492/+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

[Ubuntu-x-swat] [Bug 1173492] Re: XRandR cannot set "scaling mode"
Seeing identical behavior running Xubuntu 12.10 & 13.04 on an IBM Thinkpad T60. Scaling mode quit working when updating to kernel 3.5.0-27 on 12.10 and continues to not work on 13.04. Default resolution for this panel is 1024x768; switching to either 800x600 or 640x480 results in a window of that size at the top-left of the screen with black borders below and to the right. Confirmed that booting with the 3.5.0-26 kernel in 12.10 resolved the issue and scaling resumed working. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/1173492 Title: XRandR cannot set "scaling mode" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1173492/+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
