2 problems after installing LL 4.0 - TMG1961 - 06-03-2018
I decided after some problems to go for LL 4.0 Did want to stay with 3.8 but rather then do notting i am trying to get the problems solved.
The installation worked fine, system boots but there are 2 problems i cant get solved and need some help with.
1st problem is:
When i boot up the laptop i get error messages. But it boots anyway. The display resolution is 1366x768.The messages i get are:
error: no suitable video mode found.
error: no video mode activated.
error: no video mode activated.
2nd problem:
I cant get the Trim on SSD to work.I followed the steps in the manual.
When i do sudo leafpad /etc/rc.local the rc.local file is empty, notting in there.Copied and paste the info from the manual and edited it to my disc setup
When i do the last command to disable weekly cron job for Trim, i get the following message
sudo mv -v /etc/cron.weekly/fstrim /fstrim
[sudo] password for theo:
mv: cannot stat '/etc/cron.weekly/fstrim': No such file or directory
After reboot there is no trimlog

I have made changes to /etc/default/grub
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
Changed the above to
# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console
Updated grub after saving changes and closing the file
I don' t get the no video mode or no suitable video mode errors anymore, laptop boots up fine.
Not sure if it is a good solution, maybe the experts can shine a light on that.
Trim still not working

I and others more than happy to help you with this, but we need to make sure you're committed to fixing this and seeing it through to the end. In the Announcement thread you have changed your mind a number of times. Thank you

Hi Jerry, i do apologize for the yes LL4.0 and then again back to 3.8. This time LL 4.0 is here to stay, not going back.
I had a good nights sleep over it and this morning i made the decision to go all the way for LL 4.0.
I even deleted my Timeshift backup of 3.8 Did make a backup of Home Folder first.

Let's set aside the video message, it's gone, and I'm happy with that.
Trim - takes us through the steps you used to enable it. Remember, details = quicker, more efficient solution. Also list the partitions you have trim set on.
Re: 2 problems after installing LL 4.0 - TMG1961 - 06-03-2018
I followed the steps in the help manual to set trim on SSD.Did follow them exactly.
Steps i did
1. sudo cp /etc/fstab /etc/fstab_bak-notrim
2. sudo leafpad /etc/fstab
3. added noatime, saved file and updated grub
4. sudo leafpad /etc/rc.local .... the rc.local file was empty when it opened with leafpad
4a. added the info from the yellow box in help manual and made it match my setup
5. sudo mv -v /etc/cron.weekly/fstrim /fstrim...outcome was mv: cannot stat '/etc/cron.weekly/fstrim': No such file or directory
This is how fstab file looks after adding noatime,
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=f41a07f7-132f-4329-8c59-1c2688f71407 / ext4 noatime,errors=remount-ro 0 1
# /home was on /dev/sda5 during installation
UUID=4d493d83-feee-4ed6-b206-13367b0cc31c /home ext4 noatime,defaults 0 2
/swapfile none swap sw 0 0]/code]Re: 2 problems after installing LL 4.0 - Valtam - 06-03-2018
Upon further research, looks like trim is now a systemd service that runs automatically every week in 18.04 (4.x LL)
See here for further info - https://askubuntu.com/questions/1034169/is-trim-enabled-on-my-ubuntu-18-04-installation/1034176?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa
So for now, undo your fstab changes (carefully), delete the rc.local file. I'll update the Help Manual today.
This is Solved.

Thanks Jerry, undid changes to fstab and removed the rc.local file
I guess i can also remove the file /etc/fstab_bak-notrim ?
