Phoronix IRC Log: 2009-04-26
Shappie_: Hi all. I have a problem with my dualscreen setup (fglrx ati driver, ubuntu 9.04 final). I was redirected to this channel from the ubuntu channel.
Shappie_: I have 2 screens enabled but they act like 2 separate screens.
Shappie_: I cant move windows from the one to another. But i can move my mouse on both screens (if i leave screen 1 it stops cursor at the border and then i get the cursor on screen 2 in use. I got 2 cursors...)
Shappie_: I looks to me like a mix of cloning and big desktop...
Ivanovic: sounds more like a plain setup of two screens
Ivanovic: have you specified xinerama/huge virual desktop?
Ivanovic: IIRC in recent versions fglrx is using xrandr by default, so you have to do the same as with the free drivers
Ivanovic: adding a Virtual line with the "complete resolution"
Shappie_: No i have a clean install of ubuntu 9.04. Then enabled fglrx the ubuntu way. Rebooted and entered this in terminal: sudo aticonfig --initial=dual-head --screen-layout=right
Ivanovic: (if you eg combine a 1920x1200 and a 1280x1024 screen (horizontal setup) you would need a line with this:
Shappie_: I did it the terminal way because of the Catalyst Control Center said unknown when trying to set it to big desktop...
Ivanovic: Virtual 3200 1200
Shappie_: I know Virtual in xorg.conf. I have 1680x1050 so i have to put it on 3360 1050 right?
Shappie_: I got 2 20" screens with both same resolution.
Ivanovic: with this it should be possible to run both side by side
Ivanovic: and the bigdesktop stuff in fglrx probably only works when xrandr is not active (not sure though)
Shappie_: Ivanovic: I get an error in terminal that XRandR 1.2 is enabled when i try to put overlay to 1
Shappie_: And i cant start the ubuntu options for Screen than my whole system gets very slow and the screen options wont start...
Ivanovic: no idea
Ivanovic: like i said, i am not using any bigdesktop setup and have set xrandr to off since it led to some probs for me
Shappie_: I allready added the Virtual line yesterday but didnt work :(. I will show you my xorg.conf file: http://paste.ubuntu.com/158514/
Ivanovic: (something with automatically wanting to setup a cloning between the min res my tv and my normal display agree upon, what i really do not want...)
Shappie_: But how you put xRandR off? I cant find it anywhere...
Shappie_: I allready googled for RandR off because i dont need it...
Ivanovic: in /etc/ati/amdpcsdb
Shappie_: ooh ok i will try that! Have been searching for this a few days now! ty
Ivanovic: you can only edit it when xorg is not running or changes will be overwritten at stopping it
Shappie_: So i have to boot into recovery mode?
Shappie_: and then edit that file with nano editor?
Ivanovic: no idea, i don't use ubuntu and don't know how to get into a mode without x11
Shappie_: recovery modes give you only a terminal like black white screen..
Ivanovic: (i use gentoo and always boot right into the terminal, from there i start xorg if i want to)
Shappie_: I gonna try it! I'll be back in few min.
Ivanovic: but yeah, you have to go to commandline and edit it via some commandline editor like vim, emacs, nano, joe or *whatever*
Shappie_: ok ;)
Shappie_: Where in that file i have to add that line?
Shappie_: Just the bottom?
Ivanovic: i have it below the [AMDPCSROOT/SYSTEM/DDX]
Ivanovic: and under [AMDPCSROOT/SYSTEM/DDX/RECENTMODE]
Shappie_: so 2 times?
Ivanovic: in my system, yeah
Shappie_: Thank you. I have written everything down. Im goin to reboot now. I will be back in few min to tell you the result ;)
Ivanovic: though this file is not meant to be handedited, so i don't know what is required for you
wirechief: Ivanovic: what file were you having him edit ? (i recommended he come here and missed the first part of the conversation)
Ivanovic: wirechief: read it up yourself: http://pastebin.com/d621fc368
Ivanovic: everything from him joining till you joined
Ivanovic: in general it would probably be better if he backed up the old /etc/ati/amdpcsdb file and altered /etc/ati/amdpcsdb.default adding the line
Ivanovic: afterwards removing /etc/ati/amdpcsdb so that it is automatically created from the default file
wirechief: Ivanovic i have seen others wanting to not have Rander1.2 enabled ...must be a common need..
Ivanovic: wirechief: the problem is that RandR1.2 does not support "persistent storing" of the settings
wirechief: hmm ok..
Ivanovic: so it is non trival on my system to tell it to use 1920x1200 as res cloning it on the 2nd display with 1920x1080
Ivanovic: xrandr goes for the max common res being 1400x1050, clearly not optimal...
Ivanovic: Shappie: has it helped?
Shappie: Ivanovic: It works! I had to reset xorg to ati default and then using Catalyst Control Center i enabled the big desktop mode! Thank you so much!
Shappie: So it was a confict with XRandR
wirechief: hands Ivanovic a cup a coffee
Ivanovic: Shappie: in general you could also just edit amdpcsdb.default and move away amdpcsdb (backup!)
Ivanovic: this way you would start with "real" default settings and could just configure things via amdcccle
wirechief: Shappie lots of good information here and in the phoronix forums
Shappie: wirechief: This channel is the first channel i get help with my problem. And it works now!
wirechief: yes well when i saw you needed help with ATI i knew where to send you ;)
Shappie: thank you :)
wirechief: i have gotten many tips from here myself with my ATI x1300
Shappie: im off for eating ;)
wirechief: rushes to join the surf
piksi: hi, i haven't found specific yes/no on whether radeon mobility hd 2600 is supported by the closed source driver?
piksi: trying out the ubuntu 9.04 fglrx driver resulted in messed up garbage on the screen
Kano: it should be
Kano: you can try
Kano: sudo rm -f /etc/X11/xorg.conf*
Kano: sudo dpkg-reconfigure -phigh xserver-xorg
Kano: then run my script
Kano: but first test with -p option
Kano: if it will install 9-4
Kano: sudo sh install-fglrx-debian.sh -p
Kano: if 9-4 is shown, run it without -p
Kano: otherwise forget it ;)
Kano: well if you show me lspci -nn|grep 0300
Kano: i can tell you if it will work
piksi: 01:00.0 VGA compatible controller : ATI Technologies Inc M76 [Radeon Mobility HD 2600 Series] [1002:9581]
Kano: ok, r600+
Kano: will do
Kano: in theory ;)
redeeman: i like the "in theory" comment
Kano: piksi: best would be using -z option
Kano: then reboot
Kano: because fglrx likes to lock the system, even when x is shutdown
piksi: ok, trying out now
piksi: btw since the ati driver page at http://support.amd.com/us/gpudownload/Pages/index.aspx only lists mobility radeon X**** under mobility radeons and radeon hd 2600 under radeons, in what family does that put my card exactly?
Kano: piksi: i verified that your id is supported
Kano: in 9-4
piksi: awesome :-)
Kano: i extract that info directly from the ati driver, so be sure the info is correct
piksi: ok, it's now compiled and packaged so let's see...
piksi: Kano: seems to work beautifully, ty! :-)
Kano: i can not say it works that way, but at least you see something ;)
Kano: vdrift crashes and pts does not finish because of that when you use the default vdrift settings
piksi: Kano: well... as long as my wife can play civ4 on her laptop it's enough ;-)
piksi: other laptops have nvidia cards and i'm familiar with compiling their binary drivers but not with ati
Kano: well i have got the a similar script for nvidia, same rm /dpkg-reconfigure commands
Kano: just replace fglrx by nvidia ;)
piksi: s/other/our other/
piksi: very nice of you, thanks once again :->
d2kx: Kano: it seems that there are 2.6.29 drm patches for R6xx/R7xx EXA/Xv support around now
Kano: d2kx: i dont have got a 2.6.29 kernel source anymore
Kano: but my dkms script would do if needed
Kano: dpkg --purge drm-r6xx-r7xx-support-dkms
Kano: to uninstall btw ;)
michaellarabel: Kano: Most of your "bugs" are fixed in my local tree and will be in Git when I am back
Kano: well, there is another tuning possiblity
Kano: for vdrdrift
Kano: there is a release option that disables debug cod
Kano: scons release=1
Kano: i added serveral additional debug output to track down the point of the crash
Kano: maybe disabling shaders is not the worst idea, then you could bench against oss drivers
Kano: did you add a errorlevel check after ever make run for the compileing benchmarks?
Kano: to ignore those failed results
Kano: best check it everywhere and forget failed results
Kano: no result is better than a wrong result
michaellarabel: Kano: Not yet on the compile fail
michaellarabel: btw, AMD is aware and looking into the vdrift issue
Kano: would not help older gfx cards
michaellarabel: not designing for older cards
Kano: well when you want a working benchmark suite now you have to change the suite
michaellarabel: what hardware is not working with it besides fglrx? just ones with Mesa?
Kano: i did not test mesa
Kano: but a stopping suite it the worst that can happen
Kano: then you dont need to test it at all
piksi: Kano: the nvidia script worked beautifully as well, but seems that the driver it downloaded wants to push powermizer to max all the time, fan keeps on at full speed no matter what :-\
Kano: well it is the latest beta driver
piksi: though - it's not uncommon, this quadro M1600 is supported lousily anyway on linux :-(
Kano: if you want to use latest prerelase you can use -v 180.53
Kano: best use nvnews.net to post a error message
wirechief: piksi can i give you an inquery ?
piksi: wirechief: sure
Kano: michaellarabel: will you release a fixed 1.8.2 or so
Kano: i have got not that many kanotix users who like pts, just one, but more than 0 ;)
Kano: but he needs accurate tests of course
Kano: he benchmarks bleeding edge hardware
michaellarabel: Kano: uncertain whether there will be a 1.8.2 release
Kano: he even had the idea of a 32 gb benchmark stick
Kano: the idea itself is not bad i think because then you can add all downloads on it already
Kano: 8 gb are the max downloads, you calc em wrong somehow in pts
Kano: 7,8G /media/sda1/DLCACHE/
Kano: thats really everything cached
Kano: which are standard downloads
Kano: also you changed samething lately
Kano: before it was possible to "forget" the ending /
Kano: now it is required when you dont want that pts does something crazy
michaellarabel: Kano: What does it do?
michaellarabel: yeah, reading the logs
Kano: it creates extra dirs sometimes with the partitial names of the downloadfiles
cxo: Deanjo, hey are you around?
cxo: I just got a new mobo asus m4n78-pro, sata performance really sucks
cxo: i think its a nvidia chipset
