What is the output from:If /etc/X11/xorg.conf.d/*-intel.conf exists, what does it contain?

thanks reply mrmazda - output is : BOOT_IMAGE=/boot/vmlinuz-4.15.0-20-generic root=UUID=623faa7a-8dd4-4994-9169-5ceebba7e1af ro recovery nomodeset

re
/etc/x11/xorg.conf i only have this & it contains : Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

thanks

Test removal of nomodeset and recovery from the kernel cmdline at the grub menu when booting by striking the e key, moving the cursor down to where nomodeset and recovery are present, and delete or backspace them away. This won't help until xorg.conf is renamed or deleted. With these three changes, automagic should produce expected results.

That kernel cmdline looks like it resulted from choosing a non-default Grub menu selection. If that's the case, then choosing a selection that omits them should be all that's needed at boot time, but still that xorg.conf needs to go.

If booting with neither nomodeset nor recovery by choosing an existing Grub menu selection and xorg.conf does indeed produce expected operation, and the selection made is the default, then no further reconfiguration will be needed. If however it is necessary to make the edit at runtime, or manually choose a selection that omits them, /etc/default/grub probably needs an edit of the GRUB_CMDLINE_LINUX_DEFAULT= line to exclude them, following up with rebuilding grub.cfg using grub-mkconfig or update-grub before next shutdown or reboot.

thanks - reboot & fiddle with e key loads GNU GRUB version 2.02 / no sign anywhere of nomodeset nor recovery ?!

If https://linuxmint-installation-guide...-nomodeset.png is the screen you see after boot, try pressing the tab key instead of the e key.

If it's not the screen you see, please describe the screen you see.

You might need to hold down the shift key as POST completes in order to see the Grub menu screen where you need to use the e key.

hi mrmazda - the only screen i get is blank with the LM Bookwood image to middle bottom right hand side ie... am stuck in SR mode. If ctrl alt del then get box Session - log out this session now? - switch user or Cancel or LogOut . If switch user the have to re-log in Cinnamon (Default) - does not work or Cinnamon Software Rendering that works . Terminal works .

LVM state Physical Volumes : not OK (BAD) Volume Groups : OK (Good)

FYI : $ cinnamon settings
Cinnamon warning: Software rendering detected: llvmpipe (LLVM 7.0, 256 bits)
org.Cinnamon already exists on bus and --replace not specified

if i boot to Advanced Options for LM19.1 - Linux 4.15 0-47 generic recovery mode then i have found that reboots OK without
SR mode but then usually reboots back to the same old same old !?

thanks

How are you determining whether or not you are running in SR mode? I don't have any problem getting a Cinnamon session running from the default Grub selection (neither recovery nor nomodeset) for Mint 19.1 here:I have no /etc/X11/xorg.conf and neither any monitor, device or display configuration in /etc/X11/xorg.conf.d/.

If you pastebin your /boot/grub/grub.cfg file maybe someone can spot something gone wrong.

hello from England thanks reply will revert but firstly can you say re https://linuxmint-installation-guide...-nomodeset.png is the screen you see after boot you do not mean from the cd/dvd disc but from a boot after the installation attempt !?

I don't understand what you asked here. The image at the URL I provided is of the installation media boot menu. I didn't find any image of a Linuxmint Grub menu, or GUI login greeter (LightDM?).

i think you mean by "installation media boot menu" that the image we are trying to find comes from the Install/Live DVD of LM 19.1 Cinnamon & on this initial boot this is when i should be tapping the "E"
key or TAB or shift etc ... please confirm ?

On the screen in the image, after the menu appeared, the kernel cmdline ready to edit is showing, Reaching that point is the result of using the TAB key, as instructed here. This applies when the installation media is booted in BIOS/Legacy mode.

The E key is for initiating an edit upon reaching a Grub menu. After striking the E key, you should be on a screen that looks like this. This applies both when booting installation media in UEFI mode, and when booting an installed system either in Legacy/BIOS mode or in UEFI mode.

ok i got here https://linuxmint-installation-guide...-nomodeset.png from the Install/Live DVD of LM 19.1 Cinnamon shows like the picture but after the lz shows : quiet splash -- _

re /etc/X11/xorg.conf.d/. is not showing

</Y8qXwxjR>

This file is blocking use of any competent DDX driver, forcing use of the crude and painfully slow VESA driver instead of any driver supporting Cinnamon. You must either remove the whole xorg.conf file, or remove the line 'Driver "vesa"' from it, preferably the whole file.

ok thanks mrmazda removed said file : sudo rm /etc/X11/xorg.conf = & checked has gone rm: cannot remove '/etc/X11/xorg.conf': No such file or directory - i checked its gone restarted up to same old same old i.e $ cinnamon settings

otu thanks help

try this one?! : http://dpaste.com/2G4FNYD hurrah something worked !

also discovered mrmazda i appear to have a mix up re primary & non primary desktops have picture that explains why i see what i see : https://imgur.com/a/lACGUyL the righthand is what i see !
