Drivers after 270.41.19 do not work in twinview mode

Hi,

IBM Lenovo W510 with NVidia Quadro FX880m.

Latest driver working for me is Linux-x86_64 270.41.19.

With drivers 275.09.07, 275.19 and 275.21 nvidia-settings lock asa I try to enable twinview on 2nd monitor (I have 2 HP Compaq LA2405wg connected to Lenovo docking).

When will this issue with the 275-release be fixed. Latest release note says it has but that is not my experience.

Works:

Adding 280.13 to the list. When will this be fixed?

Licaon · 09-02-11, 12:27 PM

285.03 too?

mooninite · 09-02-11, 02:16 PM

It must be card specific. I've run many driver versions past 270.41.19 and TwinView continues to work for me.

I believe I have a similar (maybe even the same) problem as you have. I'm running a Geforce GT430 in my computer, with identical HP monitors connected to the vga & dvi ports respectively (using twinview), and one LG 32" tv connected to the hdmi-port.

Knowing that I can't run three monitors at the same time my "day-to-day" setup consists of the two HP's, and when I want to watch something on the tv I open nvidia-settings and switch between one of my monitors and the TV (still using twinview). Then when done with the TV I just switch back to using my second HP monitor again.

This has worked perfectly for me up until (and including) 270.41.19 while newer drivers just "crashes" nvidia-settings, locks up one core in my processor at 100% (that makes it two of my eight threads running at 100% in my Core i7 860). Only way for me to get out of it is thorugh a reboot.

This happens both when I try the drivers that is available through Debian Testing repositories (that one's at 280.13 right now) and when I try to use sgfxi. I got the recommendation to try the beta drivers, and if that won't work... guess I have to try and put together a bug report (I'm not sure I understand how to proceed with that one, but one step at a time)

Posted a bug report to Nvidia and the reply I got is that they're aware of the (at least my) problem with nvidia-settings crashing when trying to set twin view.

A recommended fix until they've taken care of this is to download the version of the drivers where nvidia-settings do work (in my case that would be 270.41.19) extract the installer by running:

Code:

sh ./NVIDIA-Linux-x86_64-270.41.19.run -x

(you might want to add "sudo" in front of that line - I have my "old" installers in /usr/src/sgfxi-downloads where I have to be root to make changes)

and then replace the faulty nvidia-settings in /usr/bin/ with the one you extracted. This works for me with the latest beta driver 285.03

Now - since my problem might not be identical with yours I'm not saying for certain that this will work for you, but at least it's worth trying, right?

BTW - Thanks to h2-1 over in the Linux Mint forums for helping me out with this one...

When are you going to fix this for Quadro FX 880m ?

Will now try the workarounds suggested.

I don't reproduce that on a F-14 x86 with current driver from rpmfusion.
Anyhow what is dramatically missing from this thread is the output of nvidia-bug-report.sh

Anyhow what is dramatically missing from this thread is the output of nvidia-bug-report.sh http://www.nvnews.net/vbulletin/showthread.php?t=46678 __________________ Repository for Fedora and blog (french) RPM Fusion packages for Fedora

App Launch Panel Taskbar dissapears, same Desktop is shown in both. restarting (Ctrl+Alt+Del) without saving x.conf, works again single view, but... Twin View it's very unstable... i have other pcs with ATI HD6970, works OK. before installing the latest 285.05.09 uninstalled the Nvidia-common, blocked the Neuvau, Installed in Grub recovery SafeX console mode. (X Level 3) $ sudo sh NVIDIA-Linux-x86-280.05.09.run didn't let Nvidia configure, as suggested by installer. the NVIDIA-Common drivers 270.xx synaptic repo... Twin/view has additional bugs... the _ [_] X dissapears. restarting does not fix the issue.. the only way it's to Grub - Recovery Kernel - SafeX - Restart X. other bugs: System Monitor 2.28.2 does not appear. Terminal also does not appear.
