Suspend -> change resolution

Help Desk General Help

Hey guys!

Need your help.

I’ve experienced problems with networking after suspend.
Solved that with:

PROGNAME=$(basename “$0”)
state=$1
action=$2

function log {
logger -i -t “$PROGNAME” “$*”
}

log “Running $action $state”

if [[ $state == post ]]; then
sudo modprobe -r sky2
&& sudo modprobe -r skge
&& log “removed eth”
&& sleep 1
&& sudo modprobe -i sky2
&& sudo modprobe -i skge
&& log “inserted eth”
fi

sudo cp -r ~/Downloads/eth-refresh.sh /lib/systemd/system-sleep/eth-refresh.sh

chmod +x /lib/systemd/system-sleep/eth-refresh.sh

And this works flawless on my current Elementary OS.

Now, I’m experiencing another problem with resolution, it is blurry and almost not readable.
I’ve tried with same solution:

PROGNAME=$(basename “$0”)
state=$1
action=$2

if [[ $state == post ]]; then
xrandr --output DVI-0 --mode 1440x900
&& sleep 3
&& xrandr --output DVI-0 --mode 1680x1050
fi

sudo cp -r ~/Downloads/res-refresh.sh /lib/systemd/system-sleep/res-refresh.sh

sudo chmod +x /lib/systemd/system-sleep/res-refresh.sh

^ but this does not work.

Than I’ve tried with service:

[Unit]

Description=Fix resolution blur after resume from suspend
After=suspend.target

[Service]
User=root
Type=oneshot
ExecStartPre=xrandr --output DVI-0 --mode 1440x900
ExecStart=xrandr --output DVI-0 --mode 1680x1050
TimeoutSec=0
StandardOutput=syslog

[Install]

WantedBy=suspend.target

sudo cp -r ~/Downloads/susres.service /etc/systemd/system/susres.service

systemctl enable susres.service

^ and even this does not work.
But when I change resolutions manually form the terminal, it just works.

Can you please take a look on this and tell me where I might be wrong / what I’m doing incorrectly?

Thank you in advance! :wink:
