    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    While I was looking for that., I found the work-around solution in Launchpad Bug #10002429 on this same problem in Precise, which this user should sign into and join as affected:
    https://bugs.launchpad.net/ubuntu/+s...x/+bug/1002429
    Type in a terminal:
    sudo nano /etc/default/grub

    find the line:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

    and change it to:
    GRUB_CMDLINE_LINUX_DEFAULT="reboot=pci quiet splash"

    perform via the Terminal:
    sudo update-grub

    and reboot the PC.

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Ok, this is surely the most bewildering action I have undertaken under any operating system. It makes me wonder if Linux Mint is not fatally flawed, but then I do not wish to go back to Unity either.

    I am tempted to re-install Mint Cinnamon, but if installation self-destruction is to be expected under Mint, then I had better learn how to fix it, or give it up.

    So....
    I am on post 1, Step 3. I cannot boot from rescue mode. After some quick messages I get to a blank black screen.
    How to I use step 4 to verify that linux kernel will boot??

    thanks,
    mdm


    Step 4, I tried recovery mode, and get to the Recovery Menu.
    "Drop to root shell prompt"
    And get a prompt:
    blacktower ~ #

    I enter "sudo service gdm start"
    response: gdm: unrecognized service.

    then: "sudo service lightdm start"
    response: blank screen with blinking cursor

    What do I do now?

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hi!, motomixon,

    What distribution and version are you using?

    After 'sudo service lightdm start', from the blank screen, press 'Ctrl+Alt+F1'; it should return you to the TTY console and show some error messages, or an indication of at which point it hung.

    If it does not, run:
    Code:
    sudo service lightdm stop
    startx
    and Post the results as above.

    [ If required, 'Ctrl+Alt+F7' would return you to the GUI screen]

    Chao!, bogan.

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    motomixon-

    Mint is still Debian Linux. Unix and Linux use the same graphics layers... Just some different specific parts varying from distro to distro.

    Current Mint uses lightdm now, so starting X from the commandline would be
    Code:
    sudo service lightdm start
    Go the this post for reference:
    Booting into a Text Console

    To see if you can boot your installed kernel into a text console. If it doesn't boot, reinstall the kernel by chrooting in from a LiveCD (Post #3).

    If it does boot, the problem is then in a higher graphics layer. First thing to do at that point (which a working kernel), is to look at the logs (Post then here for us to see from a LiveCD if possible).

    The first would be to look at the last 25 lines or so at the end of the syslog:
    Code:
    dmesg | tail -n 25
    "-n 25" tells tail the number of lines. If you don't see an error there, then:
    Code:
    dmesg | tail -n 200 | grep error
    Or before trying to start a graphics session from the Mint tty... Start tracing the syslog by getting into another tty session and start a trace:
    Code:
    dmesg | tail -f > ~/systrace.txt
    Then go to another tty session to start X. At the crash, switch back and press <cntrl><C> to stop dmesg. Then cat the file to review it.

    The other log to look at and post here would be /var/log/Xorg.0.log...

    Does that give you enough info to start?

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hey Bogan!
    thanks for the reply.

    "the distribution..." my oversight!
    Linux Mint 14.1 Cinnamon

    Because it is Mint, I am unclear as to which display manager I am using: Lightdm or MDM? It would interest me to learn a command that would reveal which one is currently loaded -- but that's (maybe) a side topic.

    Last night (before giving up for a night's rest) I entered at the linux prompt:
    sudo service mdm start
    reponse:
    * Not starting MDM Display Manager: it is not the default display manager

    Now, 10 hours later I entered:
    sudo service lightdm stop
    reponse:
    stop: Unknown instance

    And to continue wth the rest of your suggestion:
    startx

    And the GUI appears!! (Very magical) Thanks!
    But....
    I suppose I need to get into the interface and fix/replace my current GPU driver before I do another reboot. How do I check/correct my video driver?

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Please post the /var/log/Xorg.0.log.... That would have what drivers it tried, and what it is using on the current running GUI.

    Also if you could post the results of:
    Code:
    lspci -vnn | grep VGA
    That would tell us the video hardware that is installed.

    Also-- If you start it up and let it crash, then restart it into the GUI... post the /var/Xorg.1.log... That would be the previous session and the ones with errors so we can see what it was trying to use when it failed.

    Make sense?

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Hi!, motomixon,

    The fact that you got:
    Code:
    sudo service lightdm stop
    reponse: 
    stop: Unknown instance
    shows that lightdm was installed but not then running. Had it not been activated it would have given the same as you got with gdm:
    I enter "sudo service gdm start"
    response: gdm: unrecognized service.
    To check your video driver run:
    Code:
    uname -r
    lspci | grep -iA3 vga 
    glxinfo | grep -iA2 openGL 
    /usr/lib/nux/unity_support_test -p
    I do not want to get lines crossed with MAFoElffen and he can better explain than I, why 'startx' will open a GUI, when lightdm will not.

    Chao!, bogan.

    I have zipped and attached the Xorg.0.log file as it won't fit within a message.
    Since I could start the GUI with startx, I haven't followed all the instructions, since it appears to me I (we) have already made some headway in the problem. Let me know if I should make use of some of your earlier suggestions.

    A side question: on the left of lines of the logs is what looks to me to be a date/time stamp (??). How do I interprete those?

    Re: Graphics Resolution- Upgrade /Blank Screen after reboot

    Well, I rebooted (gulp) and it crashed.
    Then I restarted and am now at the grub menu.

    How do I proceed so that I do not overwrite the Xorg.1.log inadvertently?

    You won't, it will get relabeled as Xorg.2.log.
