[Ubuntu-x-swat] [Bug 972294] Re: Precise GMA500 screen resolution and flicker
The flicker problem on 14.04 is connected to the gma500_gfx.ko kernel module.

[Ubuntu-x-swat] [Bug 972294] Re: Precise GMA500 screen resolution and flicker
I have an ASUS Eee PC 1101HA. Aside from the Atom Z520 processor it uses a GMA500 embedded graphics card which is part of the SCH US15W chipset, also known as Poulsbo. The interesting thing is: Ubuntu 12.04.4 LTS works out of the box and is reasonably fast. Now I installed Ubuntu 14.04 LTS and graphics is alsmost unusable. Also, it has a flickering from the start that I could not get rid of. This specific 14.04 bug has already been reported: https://lists.launchpad.net/gma500/msg00719.html But since this is a mail archive, I wasn’t able to send a follow-up.

Is it somehow possible to remove the flickering?

Updating my last post 1) Resolution problem The screen.conf workaround posted before seems to be completely reliable. No more resolution problems until now. 2) Brightness control to reduce flickering As a matter of fact 'pci=noacpi' is not necessary.

[Ubuntu-x-swat] [Bug 972294] Re: Precise GMA500 screen resolution and flicker
I can confirm this bug with the same machine: non-native resolution and flickering, after installing the beta2 this morning. A workaround for installation is to resort to the alternate-CD. Rebooting after finishing installion ends in black screen, but changing then into a console w/ CTL+ALT+F1 and restarting lightdm (sudo service lightdm restart) makes login screen accessible. Choosing there 2D- Desktop opens the Unity desktop, without artifacts, but with the wrong resolution and the slight flickering already reported by @Svante. gnome- settings-daemon does not provide other resolutions. By the way, adding console=tty1 to grub default options does not resolve the problem, neither updating all the packages at their last version. I keep investigating just in case, though kernel freeze is already done. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-psb in Ubuntu. https://bugs.launchpad.net/bugs/972294 Title: Precise GMA500 screen resolution and flicker To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-psb/+bug/972294/+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 972294] Re: Precise GMA500 screen resolution and flicker
More tests: I've been able to reproduce the random behavior reported by @Svante. Sometimes the native resolution mode of the monitor (1366x768) is recognized, sometimes it does not, and the system falls to 1024x768. As a workaround I've created a typical screen.conf section in /usr/share/X11/xorg.conf.d Section Screen IdentifierDefault Screen Monitor Configured Monitor Device Configured Video Device SubSectionDisplay Virtual 1366 768 EndSubSection EndSection From then on I have not experienced the problem. Being a random behaviour it is dificcult to confirm the efficacy of this fix without a more thoroughly examination of log files and so on. As to flickering, I think it is much less noticeable at reduced backlight levels. Backlight control is not activated by default in these Vaio machines. It must be pass a paramater from grub.

All as described happened the first time i ran the Try Ubuntu. I shut everything down and did everything exactly the same a second time to confirm and write this bug report. Afterwards I have tried 2 more times (also exactly the same) and the screen resolution worked both times (nolonger an issue). BUT - The Try/Install page is always split in the middle and the far top of the screen keeps flickering as described (to be exact, the entire screen is flickering with seemingly diagonal lines moving across light purple/orange/gray areas - difficult to describe but annoying to such degree that is affecting usability - almost as much as Unity :-). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/972294 Title: Precise GMA500 screen resolution and flicker To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/972294/+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
