I posted on Upgrade Warnings a while back but have had no response.
I've been running aptosid on this Dell machine for a while with two screens and until the kernel upgrade to 3.3 everything worked fine. Since then every kernel up to today's 3.3-1 produces the same result: In console both screens show the output from the command line but starting X renders one blank.
Dual head works fine under 3.2-11.slh.3. I'm using the nouveau module and don't have any proprietary nvidia stuff installed.
card is nVidia Corporation G72 [GeForce 7300 LE]
I noticed today libdrm-nouveau1a was upgraded which gave me cause to hope it may fix it but sadly not. This is clearly an X problem related to nouveau but I'm out of ideas on how to troubleshoot this.
Thanks
Thanks |

It occurred to me that I'd posted the /Xorg.0.log having booted into 3.2.11 kernel which wasn't the brightest move  Attached is the file generated by 3.3 kernel |

| Hi, this is the relevant info:
Code:
[ 67.847] (EE) Screen(s) found, but none have a usable configuration.
[ 67.847]
Fatal server error:
[ 67.847] no screens found
[ 67.847]
Please delete /etc/X11/Xorg.conf and all files in /etc/X11/Xorg.conf.d/ and try again. Use xrandr to configure your dual monitors.
Greetings,
Chris |

Thanks Chris
I didn't have an /etc/X11/Xorg.conf or /etc/X11/Xorg.conf.d. So I rebooted after a dist upgrade and then ran:
Code:
$ xrandr --output VGA-1 --mode 1024x768 --pos 1024x0 --output DVI-I-1 --mode 1024x768 --pos 0x0
The unuseable screens error seems to have gone:
Code:
/var/log$ cat Xorg.0.log | grep EE
[ 17.864] Current Operating System: Linux Enobarbus 3.3-1.slh.2-aptosid-686 #1 SMP PREEMPT Thu Apr 5 04:39:20 UTC 2012 i686
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[ 18.538] (II) Loading extension MIT-SCREEN-SAVER
[ 18.826] (EE) Failed to load module "nv" (module does not exist, 0)
[ 18.862] (EE) Failed to load module "fbdev" (module does not exist, 0)
But there is still nothing showing in the left hand screen |

| I am not an "expert", by any means, but is the line "Failed to load module "nv" (module does not exist, 0)" indicating that nv was not completely removed? (The module was removed, but why would it expect to load it if you are using nouveau?) |

| Since xserver is trying all matching drivers, this message is normal. |

I'm still having to use the 3.2.11 kernel because every 3.3 kernel gives me the same problem. The only errors in Xorg.0.log are failure to load nv and fbdev modules. Running xrandr produces a slight temporary flicker on the LH screen but nothing more, as does changing the display resolution or refresh rate through XFCE Display settings. The monitors are identical although the one which is blank is connected via a VGA to DVI connector.
Am I destined to run this kernel forever to have a usable system? |

SOLVED!
I've been running on 3.2-11 for weeks because of losing the second screen on every 3.3. kernel I upgraded to. Today, having not upgraded for a while, the kernel was upgraded to 3.4-1.slh.3-aptosid-686 and lo dual head has returned.
Confused as to why but very happy
Thanks
PS I tried to post a full reply with SOLVED in the subject but it kept throwing a PHP error. Be grateful if some would edit the subject line accordingly |

I've removed the multiple/ identical posts.
[I have no multi-head capable nvidia graphics cards over here, even less anything remotely recent; dual-head was working fine on radeon and intel cards using 3.2, 3.3 and 3.4, basically everything I remember, though]
The reason for that PHP error is because our mail server occassionally (more often lately) can't answer quickly enough, the message will still be posted and while very annoying, the consequences are mostly cosmetic. |
