    Low resolution after upgrade

    I have an old Dell M70 (32b) that was happily running 16.04. I upgraded to 18.04 and everything went fine except of a display issue. The max resolution is 1920x1200 but I only get 1280x1024 that is very distorted. The machine has the graphic subsytem Quadro 1400G gfx. Looking around I see that the proper proprietary driver is the Nvidia-304, and this does not appear in the synaptic list nor when I click on the "Additional Drivers" tab of the software updater. I tried getting it from the repository ppa:graphics-drivers/ppa and the driver appears but it is unable to be installed because of unmet dependencies:

    I don't really care about getting the best performance but at least get the max resolution, shouldn't the nouveau driver be able to cover that?

    Thanks

    Re: Low resolution after upgrade

    I guess where do you source that you should be on nvidia-304?

    Have you tried a newer nvidia driver. I'm currently on nvidia-driver-435. It seems to work well. 440 does not work as well for me.
    Quadra is listed as supported by the newer driver. Though I can't seem to find your specific 1400G version.

    I got it from https://packages.debian.org/sid/x11/...y-304xx-driver, I tried with the 340 and the machine wouldn't boot falling into a loop - I had to chroot to purge that driver.

    not 340 driver. 435 driver.

    The nvidia-driver-435 does not appear in my Synaptic list, remember that this is a 32b machine - when I list this in another 64b machine I see it.
    I assume that the installation disk doesn't use the Nvidia proprietary drivers, but the Nouveau, and booting with this recognizes the proper maximum resolution of the machine. So my question is how to configure the Nouveau driver to properly recognize my display.

    I can't be too much help there. Well beyond my knowledge.

    But maybe try the latest x86 Nvidia driver. (384.111)

    No problem - I think I want to stick with the Nouveau driver - I think someone around should know the subject.

    Thanks anyway

    The nouveau driver just isn't as good at automatically detecting the correct resolution as the proprietary driver is. I don't know if it's to do with requesting the EDID, or parsing it, or what, but the proprietary driver definitely has some special source that nouveau lacks.

    It does seem to be the case that only the legacy 304 branch has support for that device. That branch does appear to have been dropped from the repos for bionic. That branch is in the graphics-drivers PPA for bionic. It seems to just be a package management issue that stopped you from installing it from there.

    Code:
    sudo apt install nvidia-graphics-drivers-304
    might give you more details on where exactly the issue is.

    When you were using the installer, I suspect that it was actually using 1920×1080. For a while now the installer has taken a punt on 1080p rather than what the BIOS set it to if it can't detect the resolution automatically. If you want to manually set the resolution because it's not been automatically detected, a snippet that describes the capabilities of your monitor in /etc/X11/xorg.conf.d, particularly the HorizSync and VertRefresh values, should help. You can generally find those values in the specifications or manual of your monitor.

    Re: Low resolution after upgrade

    As I said, this was an upgrade and not a fresh installation. Enabling the graphic-drivers PPA and doing:

    I don't have a clue on how to solve this. That's why I thought that I could fix the resolution sticking with the nouveau driver. What you mentioned about /etc/X11/xorg.conf.d is not here. So I don't know where to start from.
