[opensuse] how to extract and utilize kms settings?
my son just got me a 27" qnix led flat panel, 600 x 340 mm, 2560 x 1440 res. as usual, doze sees the res and does the res. but i like suse:) I have tried fresh dvd, livecd and netinstall of 11.4,12.1,12.2.12.3 in kde3, kde4,xfce, and one time i even tried gnome. The "only" setup that allows my nvidia gt240 card to feed 2560x1440 to the screen is the 12.1 -kde3 livecd, with * only non accellerated* nouveau drivers. ALL other suses default to 1600x1200 once nomodeset is added in grub, or they just bring up a blank screen. There is *no* modeline or any other setting *anywhere* in /etc/X11, so I am left wondering how I can find the kms settings of the 12.1/kde3 setup and feed them to another system, or even a different video driver, perhaps with kms killed. the basic nouveau driver is *very* slow thanks in advance, d. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Why do you think you need nomodeset? Nomodeset turns off KMS, which is the only way the most widely used FOSS video drivers, including nouveau, can function.

X can virtually always autogenerate appropriate modelines as long as EDID is valid or HorizSync and VertRefresh are provide via config file.

With nomodeset on cmdline you're not using nouveau. It's the VESA driver that's well known to be slow, and limited in available resolutions among which are not included widescreen modes much less high density modes. -- "The wise are known for their understanding, and pleasant words are persuasive."

In my battle with the "sis" drivers I found that some chips simply would not work with my larger flat panel displays, but those that could work needed ONLY a :::::::::::::: /etc/X11/xorg.conf.d/50-monitor.conf :::::::::::::: Section "Monitor" Identifier "Default Monitor" # HorizSync 28-91 # uncomment and adjust as desired (optional) # VertRefresh 55-120 # uncomment and adjust as desired (optional) HorizSync 30-81 VertRefresh 50-65 EndSection You *may* want a Option "PreferredMode" "2048x1536" or something like that in there. But I wouln't bet on it, not if EDID is working properly and you have a decent card. The "sis" is certainly not "a decent card"!!! -- The graveyard is full of indispensable men. - Charles de Gaulle -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

the nomodeset command was used when there was no screen visible or a garbled screen. As mentioned, the only time the nouveau driver found the true 2560x1440 resolution was with the kde3-suse 12.1 live-cd. that os is installed. This email is being sent from that system. right now I am *not* using nomodeset. but trying to run google-earth on the nouveau driver is like pouring molasses in Alaska in February:) trying the accellerated nouveau also fails, the propriatory nvidia drivers fail as well, that's with kms disabled and nouveau blacklisted. so i need to find just what the current settings are and then I must try to transfer them to either the accellerated nouveau driver or the nvidia driver. <clip>

well, nvidia defaults to fb, that much i know, don't know what nouveau does, but, as stated above, that is not the issue. i am not using nomodeset right now.

What version of NVidia driver is failing. I have a laptop which will not use anything > 304.60 do to the age of the card. And I have to use nomodeset or the fb screen is scrambled. -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

well, i have the nvidia community repository installed, i usually try the latest from there. my video card is a little old but it should still be ok, it is a gt-240. i tried the legacy, the g01 and the g02 drivers. no luck ( it should be the g02). but i just read something about nouveau.nomode or something like it that must be added to grub on top of blacklisting nouveau, so i have something new to try tomorrow. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The original double question still remains. 1. How can one extract kms settings in kms kernels? 2. how can one pass kms parametrers to the kernel? thanks in advance, d. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It sounds like Documentation/EDID/HOWTO.txt in the kernel source directory, might be a good read for you. Mark -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
