[RS690] Funky blinking coloured horizontal lines

[Jean.c.h]

Funky blinking coloured lines horizontilly on the screen. Appears at log in and on the desktop.

[Jean.c.h (slug71)]

Am using Ubuntu Intrepid Ibex Alpha 3 fresh install with all current updates.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.
The screenshot you attached looks ok. There are no funky coloured horizontal lines. If you have a camera you can make a photo. Do you use a CRT or TFT? Did you tried to reduce the refresh rate?

[Jean.c.h (slug71)]

If i run those commands in terminal, ie. /var/log/Xorg.0.log or any of the others i get permisson denied. Sorry im still quite new to Linux/Ubuntu.
Its a LCD on a Laptop.
It only happens every so often. Sometimes i can log out and log back in and itll be fine, other times not. When i reported the bug it did it 3 times in a row after rebooting.

[Benjamin Drung (bdrung)]

/var/log/Xorg.0.log is a file and not a command that you can type into a terminal. Please attach this file to the bug report and /etc/X11/xorg.conf too.

[Jean.c.h (slug71)]

got ya, thanks and sorry again.

[Jean.c.h (slug71)]

A couple pics from a digital camera, sometimes the lines can be 3 times as bad. Can hardly see anything/

Looks like a driver problem. I have classified this bug as a bug in xserver-xorg-video-ati. Can you run "xrandr > xrandr.log" and attach the resulting xrandr.log file to the bug report?

[Jean.c.h (slug71)]

Heres the xandr log. Tried to send it earlier but xserver crashed after i had to restart because my mouse locked up.

[Benjamin Drung (bdrung)]

I assume that your TFT has the widescreen resolution of 1280x800. xrandr output looks good. Does your TFT work hardy or with other operating systems? If not it could be a hardware defect. Three years ago my TFT had vertiacal red lines and it was a hardware fault.

[Jean.c.h (slug71)]

Worked fine on Hardy and still with Vista(Dual Boot) and yes its 1200x800.

[Tormod Volden (tormodvolden)]

Can you please attach an Xorg.0.log from Hardy (when it worked)? This looks like PLL issues, some of which were recently fixed upstream. Would it be possible for you to try out a test package from https://wiki.ubuntu.com/XorgOnTheEdge on Intrepid?

[Jean.c.h (slug71)]

I can try the test package but i no longer have Hardy installed as Intrepid replaced it.

[Jean.c.h (slug71)]

Which one of the test packages should i use?

[Tormod Volden (tormodvolden)]

> I can try the test package but I no longer have Hardy installed as Intrepid replaced it.

If you can run a Hardy live CD that would be perfect.

> Which one of the test packages should I use?

xserver-xorg-video-ati_6.9.0+git20080815.a55e85f7-0ubuntu0tormod_i386.deb
xserver-xorg-video-radeon_6.9.0+git20080815.a55e85f7-0ubuntu0tormod_i386.deb

[Jean.c.h (slug71)]

Have installed it, and will give it a try. Will run the Hardy Live CD too.

[Jean.c.h (slug71)]

Heres the Hardy Xorg.0.log taken from the Live-CD.

[Tormod Volden (tormodvolden)]

Yes, the PLL values are calculated differently:

Intrepid:
freq: 69300000
best_freq: 69298571
best_feedback_div: 813
best_ref_div: 12
best_post_div: 14
(II) RADEON(0): crtc(0) Clock: mode 69300, PLL 69290
(II) RADEON(0): crtc(0) PLL : refdiv 12, fbdiv 0x32D(813), pdiv 14

Hardy:
freq: 69300000
best_freq: 69313613
best_feedback_div: 1152
best_ref_div: 14
best_post_div: 17
(II) RADEON(0): crtc(0) Clock: mode 69300, PLL 69310
(II) RADEON(0): crtc(0) PLL : refdiv 14, fbdiv 0x480(1152), pdiv 17

These calculations have been refined upstream, so please test the 6.9.0+git20080815 version.

[Jean.c.h (slug71)]

Have it installed and no problems so far. Will try it a few more days and see how it goes before i test out 32bit Intrepid.

[Tormod Volden (tormodvolden)]

This was most likely fixed in http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=92ee21df344a989778e37369c7beb3904a00ead6

[Jean.c.h (slug71)]

ok, just making sure youre aware im running 64bit Intrepid.

[Jean.c.h (slug71)]

Just did it again

[Jean.c.h (slug71)]

pic 2

[Jean.c.h (slug71)]

Just installed the RadeonHD package from https://wiki.ubuntu.com/XorgOnTheEdge too.
Will see how it goes now.

[Tormod Volden (tormodvolden)]

Please attach the new Xorg.0.log. Thanks for the pictures, this seems worse than the first pictures.

Originally reported in Ubuntu: "Funky blinking coloured lines horizontally on the screen. Appears at log in and on the desktop."

This was not a problem in Hardy (radeon 6.8.0), but came with Intrepid (radeon 6.9.0). Same with current git. I suspect it is a PLL issue. The logs are different:

Intrepid (bad):
freq: 69300000
best_freq: 69298571
best_feedback_div: 813
best_ref_div: 12
best_post_div: 14
(II) RADEON(0): crtc(0) Clock: mode 69300, PLL 69290
(II) RADEON(0): crtc(0) PLL : refdiv 12, fbdiv 0x32D(813), pdiv 14

Hardy (good):
freq: 69300000
best_freq: 69313613
best_feedback_div: 1152
best_ref_div: 14
best_post_div: 17
(II) RADEON(0): crtc(0) Clock: mode 69300, PLL 69310
(II) RADEON(0): crtc(0) PLL : refdiv 14, fbdiv 0x480(1152), pdiv 17

Created an attachment (id=18392)
log from 6.9.0 (bad)

[Jean.c.h (slug71)]

Hi there, ive included 2, im guessing the .old one is from before i installed the radeonhd package.
Yeh sometimes it gets bad like that. Doesnt happen as often as it is in the first lot of pics i sent.

[Jean.c.h (slug71)]

actually the previous .old log might be without the test packages because i reinstalled Intrepid yesterday.

[Tormod Volden (tormodvolden)]

Thanks. I forwarded it upstream. If you can, please subscribe to the upstream bug so that you can answer the developers' questions directly.

[Jean.c.h (slug71)]

Ok no prorblem

[Jean.c.h (slug71)]

problem that was, Anyone in particular i should subscribe to?

[Tormod Volden (tormodvolden)]

Well, the bug linked to in this bug report, right? (See the top of the page)

[Jean.c.h (slug71)]

got it thanks

[Jean.c.h (slug71)]

Solved

[Tormod Volden (tormodvolden)]

Slug71, I suppose the bug was fixed since you commented "Solved". Please reopen if I got it wrong.

[agd5f (agd5f)]

Can you try again with git master?

[Tormod Volden (tormodvolden)]

Slug71, can you please try the -ati/-radeon packages for Jaunty in https://launchpad.net/~tormodvolden/+archive/ppa ? Upstream changed the PLL code a bit and asked for feedback.

[Jean.c.h (slug71)]

This bug can be closed.

[agd5f (agd5f)]

closing due to lack of feedback.

[Bugzi09-fdo-tormod (bugzi09-fdo-tormod)]

The original reporter confirmed that it works fine now.
