Description Bryce Harrington 2010-04-05 18:10:51 UTC
Forwarding this bug from Ubuntu reporter raido357:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/548709

[Problem]
Several reporters confirm that the screen is too bright after upgrading from karmic.

[Original Description]
Ubuntu Lucid Lynx radeon driver has a bug, which causes gamma/contrast/brightness settings to be messed up.  Too bright, text boxs disappear on forms, it's like sun shining directly on display. Just hard to see things.  Menu bars or all melted to one, because of brightness.

http://ubuntuforums.org/showthread.php?t=1438810

Display is okay with Karmic Koala kernel 2.6.31-20.

Using xgamma, to lower gamma makes it worse.

My display has DVI and VGA inputs. I am using DVI->VGA adapter for ANALOG input for my monitor. The ANALOG input is too bright, like described above.

If switch to DVI, then colors/brightness/gamma are fine.

So the problem is with ANALOG output from VGA.

I tried with different DVI->VGA converter, same issue - too bright display.

I can't switch permanently to DVI, because I need DVI for other machine with HDMI->DVI adapter.

 To clarify the bug, I have added camera photos using identical manual settings of the screens from Lucid (radeon) and karmic (flgrx). Note that all images are of the same bootchart file. The images are as follows:
2149: Lucid with default settings (1.0)
2150: Lucid with xgamma set to .6
2151: Karmic with default settings (1.0)
2152: karmic with xgamma set to .6

Notice the loss of shading and detail in the Lucid shots easily seen on the init and collector rows. Although the bug may seem trivial it does affect the usability of Lucid a good deal. Please consider this a serious bug.
For additional information I use a desktop pc with an xfx radeon hd 4770 and additional info can be seen in the bootchart photos.

Another user with HD 4350 reports seeing the same behavior, also using a DVI-VGA adaptor.  Another on RV100 says they see similar symptoms and are using the analog (d-sub) connector.  A user on HD3450 sees the same, also with a DVI-VGA adapter.

I have attached a photo of 2 monitors, from 2 separate computers with the same HTML color chart, side-by-side. On the left is a Windows computer, and the right is the Ubuntu 10.04 Beta1 computer that is afflicted with this bug.

The colors on the Ubuntu page that shouldn't be white, but are displaying as such are:
Gainsboro
Lavender
LavenderBlush
LemonChiffon
LightCyan
LightGoldenRodYellow
LightGray

Notice that Lime and LimeGreen appear to be almost identical on the right, and very different on the left.

This is an issue with the TV DAC BG/ADJ values.  Can you attach a copy of the problematic video bioses and in the case of the RV100 and R420, the output of "radeontool regmatch TV_DAC_CNTL"?

This patch:
http://marc.info/?l=dri-devel&m=127052658905865&w=2
fixes the issues with R4xx cards.  For the RV100 and other older cards, I'll need to see the vbios and value of tv_dac_cntl as requested.  For r6xx, I this patch should fix the issue:

You also said you wanted to see the vbios, but I can figure out how to get that information. Is that something I need to look at during boot time, or is that something I can get any time?

Please let me know if I can do anything else to help. I am by no means an expert, but I can test stuff out if I'm given good enough instruction.

that looks correct.  Does:
radeontool regset TV_DAC_CNTL 0x07280043
help?

Any time.

You'll need the pci bus id from lspci, e.g.,
01:05.0 VGA compatible controller: ATI Technologies Inc RS690
^^^^^^^
It will have some leading zeros in sysfs.

cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

Nope, has no effect. - unless I need to restart X in order for it to take effect. (I did not restart X)

Ok, I feel inept here. I preformed the above as root, and I'm not sure what I should be posting as a result. do you want the contents of /sys/bus/pci/devices/0000:01:00.0/rom ? 

I displayed /tmp/vbios.rom, and it appeared to be a binary file. As a shot-in-the-dark, I'll add /tmp/vbios.rom as an attachment in just a moment here.

No need to restart X.  what port are you using for your problematic monitor?  VGA?  DVI?

yes.  It's a binary file.
Comment 13 Alex Deucher 2010-04-06 08:23:41 UTC
for the rv100, what connectors does your card actually have?  Also, can you attach your xorg log and dmesg output?  Perhaps it's the primary dac that's causing problems.  Can you get the output of:
radeontool regmatch DAC_MACRO_CNTL

rv100_xorg_dmesg_vbios.tgz

My video card has a single connector that looks to be a dual link DVI M1-DA. This image matches the pins on my adapter: http://en.wikipedia.org/wiki/File:M1-DA.svg
I am using a cable that goes from that dual link above, to 2x VGA. I'm only using VGA #1 on this computer. 

The output of radeontool regmatch DAC_MACRO_CNTL:
DAC_MACRO_CNTL (0d04)	0x00000000 (0)
(all the repetitive zeros that follow are excluded)

I am attaching an archive of
dmesg.txt
Xorg.0.log
vbios.rom

I not going to be able to respond here for a few hours, hope that is enough information for a while.

Does:
radeontool regset DAC_MACRO_CNTL 0x00000808
fix the issue?
Comment 16 Tim Champion 2010-04-06 09:14:31 UTC
Ok, I lied, I'm still responding.

radeontool regset DAC_MACRO_CNTL 0x00000808
fixed my problem!  It might look a little on the blue side, but that also could be just because I was so used to looking at it all washed out for so long that my eyes are playing tricks on me.  HTML colors appear to be looking right, and html lightgray is no longer displaying as white.

and am still having these problems.

The patch mentioned above for R6xxx cards appears already to have been applied to the kernel that is shipping with Ubuntu Lucid.

I just tried to copy the video bios, but I get:

Let me know if there's any other information I can provide.

I've verified that these two patches were already included in the kernel 2.6.32-17.26 this was reported against:  
http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=6a8a2d702b33c6ed5c789f21b4e89fdf221f01ca
http://marc.info/?l=dri-devel&m=127052658905865&w=2

This patch was not present in that kernel, though:
https://bugs.freedesktop.org/attachment.cgi?id=34718

Thanks, I'll forward this bug to our kernel team for further handling.

Hi, i might be dumb when applying this patch, so could you help me please. 
I have Radeon HD3650 and Samsung LCD monitor connected via DVI->VGA connector, with gamma issue in 10.04.

This is what i did:

bajic@bajic-ubuntu:/lib/modules/2.6.32-19-generic/kernel/drivers/gpu/drm/radeon$

bajic@bajic-ubuntu:/lib/modules/2.6.32-19-generic/kernel/drivers/gpu/drm/radeon$ sudo su

root@bajic-ubuntu:/lib/modules/2.6.32-19-generic/kernel/drivers/gpu/drm/radeon$ sudo patch -p1 < 0001-drm-radeon-kms-more-atom-parser-fixes.patch 

(assuming that i've allready copied patch to this folder. Is this the right folder btw .. ??? )

This is the result i get:

root@bajic-ubuntu:/lib/modules/2.6.32-19-generic/kernel/drivers/gpu/drm/radeon# sudo patch -p1 < 0001-drm-radeon-kms-more-atom-parser-fixes.patch

i own a radeon HD3450 and a syncmaster 940 nw monitor using VGA connectors and have the same problem using Karmic Koala.

i installed the Os using the safe graphic mode becouse in normal mode the display was corrupted and installation couldn't go on.

after updating the fully installed OS i activated ATI proprietary drivers to enable visual effects on desktop but the display have always been too bright. 

i am trying to apply the patch but i truly don't know how to . . . 

btw in the drivers/gpu/drm/radeon folder i can find only a file named radeon.ko is this normal?
Comment 33 Alex Deucher 2010-04-27 10:29:40 UTC
You need to install the kernel source or try a ppa with a newer or patched kernel.
Comment 34 Ondrej Zary 2010-04-27 10:53:49 UTC
I confirm that the patch in comment #17 fixes the gamma problem on my RV100:

Are you saying you are still seeing the problem?  Did you apply the patch in comment 28?  The proprietary driver only works with a certain set of kernels.

an insane idea runs through my head:
i opened atom.c and found the two sections of the code where the changes should go, what happens if i manually apply the patch modifying the file? i think that lines with a minus sign should be erased and lines with a plus should be inserted, is it right? is it dangerous? (of course it is è_é )

TY
Comment 42 Alex Deucher 2010-04-28 11:34:26 UTC
if you are using a git tree:
git am <patch>
if not, you can manually apply with:
patch -p1 -i <patch>
Alternatively, you can apply by hand. the '-' lines are removed and the '+' lines are added.
Comment 43 Axl 2010-04-28 11:43:01 UTC
(In reply to comment #42)
thanks alex, manually added the differences between the files.
i found that the atom.c was already patched except for the ", tmp;" of the first difference in both the chunks of code, anyway nothing happened and the colours on my display are still very bright.
moreover with the new kernel there is no way to activate any driver for the videocard and everithing moves really slow.

any other hint for me? willing to try anything.

at worst i will wait for lucid lynx final release and update to it, might get things better isn't it?
Comment 44 Axl 2010-04-30 03:57:36 UTC

just installed lucid lynx from a USB pendrive everything goes wonderfully but colours are still bright, do i have to apply the patch in LL?
Comment 45 Axl 2010-04-30 08:03:29 UTC
(In reply to comment #44)
checked out but atom.c still is not there, by searching the whole filesystem there is no sign of this file so patch cannot be applied.
Comment 46 Alex Deucher 2010-04-30 08:18:26 UTC
You need to install the kernel source package.  I don't know whether LL has this patch or not.

don't know if this is relevant:
- even as root i can't obtain the rom of my video card with instruction posted before.
- Atom.c does not appear anywhere in my system.
- i did any previous step using proprietary drivers but even now that i uninstalled them there is nothing different.
- radeontool instruction give always "mapping ctrl region" response.
- avivotool regmatch 0x7ef4 and avivotool regmatch 0x7ff4 give segmentation fault error.

looks like i got many strange things going on here !?!?

replace <pci bus id> with the bus id of your video card (look it up with lspci).

You apparently don't have the kernel source installed then.  Also it's atom.c (note the case).

You need to run avivotool as root.  radeontool isn't useful for your card.

here is the rom finally! thanks for the help, hope this is useful.

maybe this is not the right place to ask for it, but how can i install the kernel sources then? i did it from the package manager but apparently it didn't work.

and here is what happens with avivotool:

kbkang@kbuntu:~$ sudo -s

well i'm back, don't know why but bios was upset with my usb keyboard, now i moved it to an external hub and everything's fine again.
as of now i'm running this kernel: 2.6.32.11+drm33.2, and i applyed the patch to the atom.c file before compiling and installing the sources. but now the driver is set to the opensource ATI radeon instead of the fglrx, trying to install the wich fails always and resulting in no change in colours but no acceleration at all. i'm running out of hope...

back again. as i had no news since my last post maybe i was misunderstood. the problem is not solved and i still have very bright colours. is there anything else i can do? i will try once more reinstalling ubuntu, the kernel and the patch, but i doubt it will work... i'll give some feedback in a few days.

Thanks!

The patches have been committed to the kernel.

Maybe this bug old/obsolete, but I recently got new Radeon HD 4350, and can confirm this bug. Display is too bright with gamma = 1, lowering gamma do not solve problem because window decorations become dark, red becomes tomato, buttons on forms in browser or other apps are white (using gtk theme 'Mist'). How I can fix this?

Make sure you have a new enough kernel with the patches mentioned in this bug 2.6.34 or newer should be ok.

Yes, I have installed latest stable kernel 2.6.34. I use VGA adapter and UMS (KMS strangely freezes my X server with kernel panic when I shutdown/reboot my box. I will fix this later if possible).

I fixed issue with KMS, but bug still visible, even with KMS.

Please attach a copy of your vbios as per the instructions in comment 9.  And attach the output of the following commands:
avivotool regmatch 0x7ef4
avivotool regmatch 0x7ff4

You can get avivotool here (part of the radeontool package):
http://cgit.freedesktop.org/~airlied/radeontool/

All commands must be run as root.

The values there look fine.  Does:
avivotool regset 0x7ff4 0x00222002
help?  or

No. This don't help.
I can compare the colors with my old video card and I'm sure - the problem appears when I boot with new Radeon HD adapter.
