Groovyarcade - Attract Mode in 15khz after update

[GroggyExpulsion]

I have a Tri-Sync Nanao MS2931, after running the system update i now no longer get AttractMode in 31khz

On boot the Bios text displays in 31k, if i drop out into the terminal it is in 15k and if i load groovymame it loads in 31k

Games have no issues autoswitching.. Have looked through all the config files but can't see anything that would effect it. Can confirm monitor is set correctly in the config file

Anyone know how i can get the main UI back to 640 x 480?

[Substring]

can you give me the output of cat /proc/cmdline ?

[GroggyExpulsion]

Sorry for the poor text formatting,

[Substring]

Your default resolution is set to 320x240, can't have happened on update. Was like this before. Or you've played with boot resolution in gasetup.

[GroggyExpulsion]

Ok fair enough.  But when i run gasetup and select my monitor type - MS-2931 i am unable to change the resolution.  When choosing resolution i get "your selected monitor does not require a resolution change"

Previously choose the MS-2931 monitor would automatically set the UI to 31khz and now it defaults to 15k

[Substring]

Do you know which resolution was it running before ?

[GroggyExpulsion]

Terminal and UI used to run at 640 x 480

[Substring]

can you generate a toucbleshoot archive from gasetup and give me the link ?

So you need to edit the syslinux.cfg boot file and replace video=VGA-1:320x240S with video=VGA-1:640x480S

Do you need further instructions ?

[GroggyExpulsion]

Thanks mate. I can figure it out from here. Thank you

[Substring]

ok, just ask if you feel lost

[GroggyExpulsion]

Just one more question. Where would i change the hostname. I have two groovyarcade installs and would like to reference them by hostname

[Substring]

Just sudo hostnamectl set-hostname myhostname

[GroggyExpulsion]

when i open boot/syslinux/syslinux.cfg it does not contain the line to be edited

default arch
timeout 0
prompt 0
#UI vesamenu.c32
menu title Groovy Arcade Linux
menu background splash.png
label arch
menu label GroovyArcade
linux /vmlinuz-linux-15khz
append root=/dev/disk/by-uuid/1123aef4-437f-48f1-b17d-8746e52367c8 rw quiet rd.udev.log-priority=3 splash mitig>
initrd /initramfs-linux-15khz.img

[Substring]

It does contain it, it's at the end of the line starting with append, it's cut in your copy, see that > at the end

[GroggyExpulsion]

right you are.. didn't realise how long that line was

Thanks for the patience 

[Substring]

you're welcome
