Cannot start X after attempt to update video driver
While attempting to identify the cause of a crash in X, invoked by KMyMoney, following a change of graphics card hardware, I was advised to try another graphics driver. As a result my system start only in comand prompt mode and I cannot Startx.
Somehat foolishly I followed the Howto on installing the 'latest and greatest nVidia drivers'. The installation failed (most alarmingly because the driver that the nViida web-site identified as being appropriate - X86-256.44 - actually issued an warning message during installation telling me that it did not support my installed hardware!). The recovery recommended in the Howto also failed (as I suspected it might).
If I press Ctrl+Alt+F7 at the command prompt I get many error/warning messages, starting with multiple instances of the following pair:
"unknown parameter encountered"
"ignoring unknown pararmeter"
and the system then enters a wait after the message 'checking battery status' - which confuses me, as, aside from the CMOS battery, there is no battery on my desktop system.
If I issue the startx command I get many error/warning messages
"using config file /etc/X11/xorg.conf"
"using config file /usr/share/X11/xorg.conf.d"
"No devices detected"
"Fatal server error"
"No screens found"
"xinit: no such file or directory (errno2): unable to connect to X server"
"xinit: no such process (errno3): Server Error"
What steps do I need to take to recover?
I am using Ubuntu 10.10, with an nVidia Quadro NVS 280 card and dual screens. This was a change from using a Matrox P650 for which I was unable to get any support for dual head operation. After the change I began by using the 'recommended driver' - nVidia version 173 - as recommended in <System><Administration><Additional Drivers>. That combination worked fine until my first use of KMyMoney, which resulted in an immediate (and I mean imediate - less than the blink of an eye) crash and burn of the X system.
