floid, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.

[Ubuntu-x-swat] [Bug 1181355] Re: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p)
As a parting comment, this was awful enough and lasted long enough that I was forced to drop 6450s in the affected hardware, so I don't know if any of that was resolved. I will note the following for those in the same boat: a) Dropping in Radeon 6450s did solve it and they were only $30 or so with careful shopping at that time, probably less now that they only have half the performance of an A8's integrated GPU. b) Dropping in 6450s did generate enough heat and power stress in combination to take out the aged capacitors in one of the two machines, forcing an upgrade, which forced the issue of upgrading the other machine to match. If you're upgrading an old machine with a fanless card and there's no case fan in the usual near the card cage position, I would suggest adding one for the extra $4 or so for insurance or rubber-chicken facto. At least, in my minimal sample of these 2 machines and 2 similar Socket AM2 boxes with case fans (~80-90mm low-RPM 'silent' types) it was only one of the fanless boxes that hit death. (I will also note that the dead box had a standard 'old fashioned' power supply with a small exhaust fan and mostly slots on the back, while the boxes with no trouble have all had the 'modern' style with a large 120mm fan pulling air up across the board from the bottom. In a marginal situation this might be enough to keep things alive until the hardware is obsolete for other reasons.) c) Fingers crossed, thus far I have not been bitten with too much bitrot in the 6450 support and I believe they are recent enough to still be a target for the ongoing improvements in the open-source driver.. this year, at least. fglrx still supports them right now. d) If I had realized Socket FM2 was a dead-end at the time I ended up having to buy new machines as a result of this saga, I would've been even more annoyed. If something's gone wrong now and you're still standing by AMD, do make sure you end up with something FM2+ (not plain FM2) so upgrades to anything interesting will be possible. The Unity/Libre/Firefox stack has been gradually bloating such that the maximum 2GB in the old machines was not going to support standard browsing/multiple-documents-and-reference-PDFs-open-at-once office tasks for much longer anyway. It is never fun to be forced to upgrade hardware solely for reasons of bitrot. While I think AMD ex-ATI has better intentions of providing good and stable FOSS/*NIX support for chips of roughly the vintage of the 6450 and later, and I sure appreciate what a nightmare maintaining X.org support must be (I was also 'bitten' by the rot of support for the 'well-supported' Matrox G200 at the end of the AGP era)... I will post grumpily grumpy about this to the extent that it might shame anyone into not letting the decay repeat quite so badly in the future. (There seemed to be initial good intentions with the RS480 and 780G, but breakage in support for both forced me to invest in a lot of 6450s... even when they had previously been quite adequate and the only 3D app in use was Unity itself. It does leave the customer feeling like a sucker and I can no longer say I've had no problems maintaining a business on AMD... even if I did get to sit out a dozen different incompatible Intel CPU socket 'generations' in the time this hardware lasted, and enjoy switching from the original Semprons to some of the last Athlon 64x2 parts when the former could no longer cut it.) -- 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/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+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 1181355] Re: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p)
Reviewing state and this bug after wondering why the system wasn't flickering after a reboot, I am reminded that entering and leaving monitor sleep seems to be prerequisite to reproducing the issue. So every boot is fine until the monitor goes to sleep, and disabling it would be a workaround. ** Description changed: + [Edit: Issue narrowed down to Something Bad Happening when the display + goes to sleep. See wordy observations on how to reproduce and/or work- + around in comments ~#4-#7 in Launchpad.] + Any suggestions where to start welcome: Compaq SR1611NX desktop, Radeon Xpress 200 RS480 (R300) graphics. HP LV2311 LCD connected via VGA because that's the only output on this hardware. The VGA output used to be a little less than perfectly stable with older X.org (versions shipped from Ubuntu 9.x to 10.x). Unknown improvements since then have made the overall display much more stable - no more shifty horizontal flicker. In tradeoff, now the top half of the display occasionally flashes distractingly for fractions of a second (single frames?) with memory cruft as you might expect to see during boot or graphics init - generally offset large checkerboard-esque blocks of black and color with no obvious relation to what's on the display. This would seem to suggest it's an actual GPU/driver issue rather than a glitch on the VGA/monitor end of things. No idea how to trigger or reproduce other than that it will generally occur at least once within each 15 minutes or so of use. Expanding and retracting the dash (very slowly due to the current regression - takes about 5+ seconds to fade in and dismiss) will sometimes set it off, however. - - Recommendation for screen-recording software to see if it turns up in software short of pointing an actual camera at the screen? + Recommendation for screen-recording software to see if it turns up in + software short of pointing an actual camera at the screen?

Per multiple re-edits just now, whups, starting LibreOffice with a few documents open from autorecovery and maximizing a window has started it up without the monitor having gone to sleep since booting. Will try to pay attention and report if this puzzler is connected to Libre somehow - I'm never not running it and all workarounds described have probably been discovered/tested with it running and never killed or restarted. -- 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/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+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

Testing suggesting it's not very application-dependent: 1. With Libre started and 'flickering' occurring, kill -9 it and make sure it's dead; flickering persists while using Firefox. 2. From that state, conduct 'change mode and revert' workaround: flickering stops and does not recur after restarting Libre (prior to letting display sleep happen at least). [Also noting I am likely to give up on this and drop a Radeon 6450 card in as throwing different hardware at the problem is going to be cheaper than the time-cost. Still interested in seeing it resolved to the extent that it's regressive and also always farcical when the hardware requirements for word processing outside of vi arbitrarily go up.] -- 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/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+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

Workaround seems reproducible after a reboot, although switch to 1280x720 actually produced a working mode this time. (Rebooted to install updates available as of about 0400 UTC 2013-05-24 which contained some things tangentially related to udev, nothing that seemed likely to have graphics impact?) -- 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/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+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 1181355] Re: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p)
It appears I was confused and most recent testing _did_ happen in the same session post-reboot, see timestamps in log snippet below; The bug recurs after the display goes to DPMS standby/sleep. It also appears the display corruption on switching modes occurs after the display has its first (or multiple) chances to sleep as I hit it now flipping to 1280x720 the second time in the session - no more clear 1280x720, again a wait for a garbled screen to revert. While Xorg log shows the machine rereading DDC/EDID data when things are woken out of DPMS (and the seizure-inducing flicker recommences), xrandr shows _no_ difference in modelines before/after... not really a surprise but was worth confirming.

A possible temporary workaround after discovering the issue persists through a warm boot not starting VMWare Player, which I temporarily suspected - only been testing for about 5 minutes here: Used Displays to set 1280x720 instead of 1920x1080. Display becomes a horrible corrupt mess of offset chunks vaguely suggestive of what might be on the desktop except for a perfectly working hardware cursor. Waited for display to revert; post-reversion to 1920x1080 the seizure- inducing blipverts as shown in the images above seem gone and the desktop text is less flickery with timing cruft as well (longstanding problem using the analog output with this hardware similar to the bad old days of the Rage XL). Not sure if this implicates KMS / poor setup from KMS, as alluded to in other similar Radeon bugs. dmesg shows nothing, Xorg log shows nothing interesting from the resolution-flip operations: [ 718.155] (II) RADEON(0): Allocate new frame buffer 1280x720 stride 1280 [ 718.155] (II) RADEON(0): VRAM usage limit set to 48193K [ 748.647] (II) RADEON(0): Allocate new frame buffer 1920x1088 stride 1920 [ 748.692] (II) RADEON(0): VRAM usage limit set to 44089K Inability to successfully downgrade resolution probably counts as another bug but is not of personal interest. -- 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/1181355 Title: R300 (RS480): Intermittent flickering corruption top half of display (VGA, 1080p) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1181355/+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
