Laptop Monitor fine when booting from live usb, then fails after installation <SOLVED>

[biologopaco]

Hi,

I am trying to bring back to life a very old laptop. After booting with Mint 17.1 xcfe from the usb, things looked fine. However, after installing mint in the hard drive, the monitor (which is 1024x768) now only shows 640x480, using only the top left corner of the screen. I have tried the xrandr way to add a new 1024x768 mode, but when trying to add it to LVDS1, xrandr produces an error. Also changing the grub file by adding nomodeset or i915.modeset=0 (or 1) did not work.
In summary, screen detection works fine when booting in live mode, but fails in normal booting...

Here is the output of inxi -Fxz

The output shows no EDID for the laptop's display. A custom xorg.conf file will need to be created. Use this command to create it:

Code: Select all

gksudo gedit /etc/X11/xorg.conf

In the opened empty file, add these lines:

Log out and back in. If the resolution is not correct, then go to Settings > Display and check for it and make the change.

If there is a problem getting back to the desktop, then press Ctrl+Alt+F1 to enter the virtual console tty1. Log in and then type this command to remove the xorg.conf file:

Code: Select all

sudo rm /etc/X11/xorg.conf

Then type: sudo reboot

If you can't enter tty1, then press Ctrl+Alt+Delete to reboot and select Recovery Mode at the GRUB boot menu. If no menu shows, then hold down the Shift key while starting. In the menu, select “root - drop to root shell prompt”. When asked for the root password, just type your user password. Then change the file permissions to read and write by typing:

Code: Select all

mount -o remount,rw /

Then type this command to remove the xorg.conf file:

Code: Select all

rm /etc/X11/xorg.conf

Then type this command and wait: reboot

I am still able to access the computer as before (just hard to use with this small resolution), and the Xorg.conf file is still there, but apparently did not changed the display.
As I mentioned, I am able to get the right resolution when booting in live mode, so the display is detected correctly then. Would it be possible to use the same detection protocol used in live mode in the regular booting from the hard disk?

[roblm]

Is there an external monitor connected to the VGA port?

[biologopaco]

nope, no external monitor

[roblm]

This line is in the xrandr output and appears to be a misconfiguration: VGA1 unknown connection

Reboot and at the GRUB boot menu select the correct line but don’t press Enter. Press the “E” key to edit. If no menu shows then hold down the shift key while starting. Using the Down arrow key, go down to the line that starts with:
linux /boot/vmlinuz.............ro quiet splash $vt_handoff

Press the End key to go to the end of the line. Add a space and then add this parameter: video=VGA-1:d

Press F10 to start your system.

[biologopaco]

so after rebooting, still the same screen resolution, with this xrandr --verbose output

[roblm]

Adding the parameter video=VGA-1:d to the kernel command line will only have an effect for one session. To make the change persistent, use this command to open the grub file:

Code: Select all

gksudo gedit /etc/default/grub

Change this line:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To this:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=VGA-1:d"

Save the file and then use this command to update grub:

Code: Select all

sudo update-grub

Then open the File Manager and go to /home/your-user-name/.config/xfce4/xfconf/xfce-perchannel-xml.
Check if there is a file named displays.xml. If yes, then delete it and reboot.

Would it be possible to use the same detection protocol used in live mode in the regular booting from the hard disk?

I don't know how that could be done.

A different Modeline will be tested. Open the xorg.conf file again:

Code: Select all

gksudo gedit /etc/X11/xorg.conf

Remove all the lines and then add these lines:

Code: Select all

Log out and back in and check in Settings > Display if the 1024x768 resolution is listed.

Run a live session using the Mint installation USB stick. At the desktop, open the Terminal and use the xrandr --verbose command.

The Modeline listed is a little different, so it will be tested. Open the xorg.conf file again:

Code: Select all

gksudo gedit /etc/X11/xorg.conf

Remove all the lines and then add these lines:

Code: Select all

Section "ServerLayout"
   Identifier   "Layout0"
   Screen   0 "Screen0" 0 0 
EndSection

Section "Monitor"
   Identifier    "Monitor0"

Use this command in the Terminal and post any message:

Code: Select all

xrandr --output LVDS1 --mode 1024x768 --rate 60

[biologopaco]

Code: Select all

xrandr: cannot find mode 1024x768

[roblm]

Now this is strange. The 1024x768 mode in the xorg.conf file should be used. Try using these commands in the Terminal.

Code: Select all

xrandr --newmode  "1024x768_60.00"  63.50  1024 1072 1176 1328  768 771 775 798  -hsync +vsync
xrandr --addmode LVDS1 1024x768_60 
xrandr --output LVDS1 --mode 1024x768
