[Ubuntu-x-swat] [Bug 933289] Re: bad flickering with Radeon drivers in 12.04 Precise
This flicker is far worse on GCN hardware (Radeon HD 7xxx). The instant you boot into Ubuntu with the open source radeon drivers, there is massive amounts of black boxes flickering all over the screen. Even with xorg-edgers/ppa like above, it does not solve the issue. The only driver GCN hardware is functional on is fglrx. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933289 Title: bad flickering with Radeon drivers in 12.04 Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/933289/+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

After installing the ppa:xorg-edgers/ppa the flicker seems to have been fixed. This leads me to conclude that the issue was caused by something done in the default Ubuntu install of X. However, it would be nice to see some of the changes with the 1.12 server and drivers to be brought into mainline for inclusion, as this seems to have fixed the issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933289 Title: bad flickering with Radeon drivers in 12.04 Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/933289/+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

Another note. After completely removing the xorg.conf file, at first startup the flicker dissapeared, and, again, came back after a couple of minutes of use. Setting [Option SwapbuffersWait on] in the xorg.conf file was ineffective, and there is no difference between with or without the xorg.conf file as far as screen tearing/flickering is concerned. Also, enabling Force full screen redraw (buffer swap) on repaint in ccsm did not aleviate any flickering and only caused more artifacts and screen glitching than before. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933289 Title: bad flickering with Radeon drivers in 12.04 Precise To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/933289/+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

I have seen the diagonal tearing on just about every ATI/AMD graphics chip I've ever tried. Though I only remember seeing it with fglrx, not radeon.

[Ubuntu-x-swat] [Bug 933289] Re: bad flickering with Radeon drivers in 12.04 Precise
Britt, if Force full screen redraw (buffer swap) on repaint doesn't work then that confirms there is a problem with the driver. or hardware (probably driver). Because that option should give you flawless silky- smooth graphics so long as vsync or SwapBuffersWait support is enabled in the driver. Also, your Xorg logs confirm that you already have SwapBuffersWait enabled by default: [ 1524.476] (II) RADEON(0): SwapBuffers wait for vsync: enabled So if Force full screen redraw (buffer swap) on repaint is also enabled then it's definitely a driver or hardware problem.

[Ubuntu-x-swat] [Bug 933289] Re: bad flickering with Radeon drivers in 12.04 Precise
Britt, a few questions. First, is this a regression? If so, when did you first start noticing the flickering? You mentioned there was a recent fix released; can you supply some additional pointers as to what that fix was or when it went in? You mentioned you don't see it in Arch linux; what version of X.org, mesa, and kernel were you running there? Have you tried installing fglrx? If so, do you see the bad behavior when running that? (Note that the fglrx currently in Precise has a bug when playing video with Xv, so you may wish to uninstall it and return to the foss driver once you're done testing.) Given that you see similar misbehaviors in gnome shell and unity, it does seem reasonable to assume it is due to an X.org/mesa/kernel driver issue. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933289 Title: bad flickering with Radeon drivers in 12.04 Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/933289/+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 933289] Re: bad flickering with Radeon drivers in 12.04 Precise
This is not necessarilly a regression, as I have yet to know an experience in Ubuntu with the open sourced Radeon drivers without a fair amount of flicker. (There has been flicker since 10.10 when I first started using AMD graphics on my laptop and desktop). The bug that was filed said fixed flicker using the radeon driver with Compiz or something to that extent, but I do not know of the specifics of the package that carried the patch. (possibly a compiz patch or a Unity patch, I read a lot of changelogs and it has slipped my mind). I tried searching for the updates that I installed on the 16th of Feburary, and I installed full updates to my compiz and my unity both on the same day, so it is most likely in the changelogs for one of those projects. In Arch linux I was running the 1.11 version of X.org, Mesa 7.11, and I was running the linux kernel 3.2.0 (or some variation of that version); as arch updates so readily it is hard to know exactly which version of the kernel it was, but all times I have ran arch with open sourced Radeon drivers it has been a flawless and seamless experience. Is there any way to get any of the Ubuntu devs to try out Arch on a system with Radeon graphics to see what they are doing and possibly merge any patches they have made into mainline Ubuntu? Yes I have tried installing fglrx, that is what I am currently running as to avoid the screen flicker. I do not see any flickering behavior with fglrx, but the desktop itself is noticably slower when dragging windows and interacting with the desktop. (On a side note I have noticed that Precise still is using an old version of fglrx from a couple months ago which does not contain a lot of the fixes that AMD released for Gnome-shell integration. Is this going to be changed at all? I would like to see a more up-to-date video driver for some of the fixes.) Also, when running the fglrx driver in the system settingsdetails it registers as a VESA driver, when it is clearly the fglrx driver that is activatedbut that is a different issue ;-) I do believe that it could be a x.org/mesa/kernel driver issue, and I have seen similar flickering issues in an out-of-the-box install of Fedora 16, but in subsequent updates it seemed to have cleared up. And, like I have mentioned before, Arch linux has a absolutely fabulously working version of the FOSS Radeon stack. I would love to render any assistance that I can towards fixing this issue, but my knowledge of programing is slim at best. I am a work-in-progress when trying to learn more about patches and the bug fixing process, so I may or may not be able to help. I am mostly just reporting what I have seen with my various dabbles with other linux based operating systems, and how Ubuntu differs in my experience with them. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/933289 Title: bad flickering with Radeon drivers in 12.04 Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/933289/+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
