Issue with 14.2 and NVidia Quadro 600

I recently got an HP Z600 workstation, in which I installed
Slackware 14.2. This workstation comes with an NVidia Quadro 600 card,
with two sockets: DisplayPort and DVI. My monitor is a Samsung S32D850T,
with a maximum resolution of 2560x1440. I have installed the latest
proprietary NVidia driver for the Quadro 600, as downloaded from NVidia.

When I use the DVI connector, what I get is that things work
properly in console mode (at what seems to be 80x24 resolution) and X -
but only at 1920x1080 resolution. When I try 2560x1440, the fonts in X
are all messed up, ending up with an unusable desktop (everything is
readable only with great difficulty.)

When I use the DisplayPort connector, the console mode does not
work, in that the monitor remains blank. However, on launching X things
work fine, even at 2560x1440 resolution.

Things being the way they are, using the DisplayPort connector
the end result is acceptable. However, I am mystified about the behavior
of X with the DVI connector, and about the lack of console access with
the DisplayPort connector.

If anybody can provide feedback on how to fix either of the
issues above (the DisplayPort one being preferred) that would be much
appreciated.

For the text console on DisplayPort you probably have to blacklist
the nouveau video driver (let the nvidia proprietary one handle it)
and put a "vga=normal" in the lilo.conf as an additional kernel
parameter, to put the console into the normal 80x25 character mode.
The frame buffer FOR the console can only handle UP to 1280x1024
(VGA=795 or one of the lower color modes), which is what I'm using on
my Quadro FX adaptor). X then runs in the full 1920x1200 my monitor
is capable of.

Thanks. The nouveau driver is already blacklisted - in fact, the
NVidia installation script refused to proceed until the blacklisting took
place. I do have 'vga=normal' in my lilo.conf. I guess I could try with a
different vga value.

Do you have TwinView enabled in the xorg.conf file?

Some output modes for Nvidia cards only work if you are connected
to that output when you boot the machine. If you have monitors
connected to two different outputs the card will select one
output for the boot information. Thereafter if you start X with
Twinview enabled you will get two displays, but they may not
be identical.

I find that I have to select on output for booting the machine,
then connect the second output before starting X.

Experiment.

I can't help you but I am interested to find out if it works. I have a
Quadro card (not the same as yours) and all videos stutter with every video
player I have tried with the nVidia driver. It is quite annoying and I have
not been able to pin things down. It is a widely reported issue
unfortunately. This is one area where Windows seems less annoying.

Running Fedora it is quite the pain in the ass to keep changing grub and
trying nuveax (however that is spelled) for comparison and I didn't want to
use the open source driver, I mean the real one has to be better hasn't it?

So let us know how your Quadro works please. Thank you.

Well, I don't think that my experience is going to help you all
that much, but here it goes:

I commented out the 'vga=normal' line in my /etc/lilo.conf, and
then uncommented the line reading 'vga=790', for no other reason than,
Why not? After invoking 'lilo' I rebooted my system and, lo and behold, I
got the BIOS splash screen - something I had not been able to see with
the setup above.

The boot process complained that my selection was not supported,
and gave me 30 seconds to select one among its offerings. I think I
selected 'j', again because, Why not? I.e. I selected more or less
randomly.

After this, the boot process continued normally, with all the
output visible in the console. I launched X by hand, as usual, with
'startx -- -listen tcp' (yes, I need that) and everything still works
fine under X.

Regrettably, I do not know why the console was blank before on
booting the system, and why it is not blank now. Maybe the change in the
vga line did it but, since I saw the BIOS splash screen, I am somewhat
skeptical. I'll reboot the system in a few days again, to find out
whether the behavior described still holds.

Like I said, I don't think this is going to be of much use to you.

Thanks. I get stuttering with youtube, mplayer, vlc, several gnome movie
players. Are your videos playing smoothly? Are you sure the graphics card os
being used rather than the onboard graphics?

If you have two cards as in integrated graphics and you added the Quadro
there are many issues reported with systems not always using the card you
want and also not working in all cases. In my case there are no integrated
graphics (the BIOS sees only the Quadro and there is nothing for the OS to
choose from either) so the Quadro gets used in all cases.

It's surprising how many reports of stuttering are out there. But not many
people have Quadros. Most people reporting this seem to be using high end
GTX cards.

Everything is smooth for me and my system doesn't HAVE onboard
graphics, the Quadro FX is the only video adaptor (these HP
workstations never have on-board graphics, you have to be able to
choose what level of graphics you want on them).
We've even used workstations on which the graphics card costs more
then the system box itself (it takes up a double PCI-X16 slot and
needs its own power supply lead).

Are you using Nuveaux or the nVidia driver? If nVidia, which one? I'm using
390.25 with a 4.15-something kernel.

304.125 with a 3.10 kernel (this is a 4-year old Slackware release on
a HP xw4600 workstation, which is about 10 years old, I formatted it
first for Linux in 2010).

Same here as Eef reported. I do not see stuttering in mplayer (I only
use mplayer, so I can't comment on other players, and for any youtubes
I decided I think I want to see, I use youtube-dl to download first).

The box is a Dell workstation, no on-board graphics, Quadro card.

/proc/pci reports it as:

NVIDIA Corporation G94GL [Quadro FX 1800] (rev a1)

And I am running the nouveau driver that shipped with Slack 14.1, and
am running the card with two monitors (of different pixel sizes)
attached with one single large desktop spanning across the two).

Precision T series ??
I think the T?400 and T?500 are about of that generation.
We used to have lots of T3400's. They also were equipped with Quadro
FX cards (FX 1700, to be exact).

I used to run my previous HP (also a HP xw4600, but then at work) with
2 identical Dell 19" screens. Here, at home, I use a 26" Samsung
screen (1920x1200), so just a single monitor (don't have room on my
desk for a 2nd one).

But I always _have_ been using the proprietary nVidia drivers, of
which the 304.x is the last version to still suppport this FX 1500,
your FX 1800 could maybe use a newer one.

At one point I did attempt to load the Nvidia drivers, something didn't
work right somehow (I forget what now) and as nouveau was working just
fine before (and after I reverted) I just stuck with it. In any case,
I don't see any stuttering playing videos and everything else seems to
work fine.

A bit late to the game, for others have already given relevant
info. Anyway, here is my feedback, for completeness:

My videos are playing smoothly, but I don't really use this
particular machine to play videos, anyway. There is no onboard graphics
in this system - just the NVidia card.

When I use the DVI connector, what I get is that things work
properly in console mode (at what seems to be 80x24 resolution) and X -
but only at 1920x1080 resolution. When I try 2560x1440, the fonts in X
are all messed up, ending up with an unusable desktop (everything is
readable only with great difficulty.)
This is most likely because you have a single link DVI cable but need a
dual link DVI cable for such a high resolution.

Dual link cables have 6 extra pins in the connectors and are capable of
delivering more pixels.
Post by Clark Smith
When I use the DisplayPort connector, the console mode does not
work, in that the monitor remains blank. However, on launching X things
work fine, even at 2560x1440 resolution.
My guess is that you forgot to disconnect the DVI cable and the console
was sent to the DVI output.

happened before I even tried with the DVI cable.

Thanks guys. I wonder if the variable is which desktop. I read somewhere
sometimes the desktop interferes with video compositing. I don't understand
this but I tried using my trusty fluxbox window manager and the stuttering
was even worse than on Fedora's default gnome desktop.

You guys are reporting a mix of nVidia drivers and nouveau and nobody has
stuttering. One guy is using the same driver I am 390.25...

What desktops or wm are you using? Thanks!

Note, top quoting on Usenet is considered not-kosher.
