MX Linux Forum

Posted: **Thu Jun 15, 2023 8:52 pm**

Hello, I did a fresh install of MX. After coming back from "suspend" mode, the display is reddish throughout and is lower resolution like an old computer. This does not go away and I have to re-start. I thought this was a swap size issue so I increased swap to 2x RAM (RAM is 6GB). Any ideas? Thank you!

I saw on the forum a reference to an "intel tweak" but can't find the tweak itself. I welcome a pointer or other suggestions on this display issue. Thanks!

It won't be there also won't work. Cause your card is AMD :

Graphics: Device-1: AMD ... driver: radeon
...
Display: ... driver: loaded: ati,radeon

Maybe clarify as to whether the display issue is hibernation or suspend.

Posted: **Sat Jun 17, 2023 2:31 pm**

Code: Select all

sudo make-xorg-conf radeon -o /etc/X11/xorg.conf.d/20-radeon.conf

Reboot, try suspend then wake up.

Posted: **Sat Jun 17, 2023 3:16 pm**

I tried the make-xorg-conf command (and reboot) but the video issue remained after suspend...

Posted: **Sat Jun 17, 2023 5:12 pm**

A search of iMac7,1 v: 1.0 linux waking from suspend brings up a lot of older hits regarding this.
I don't know linux, I'm a newb, but if others of more knowledge don't eventually solve the issue, maybe try light-locker, or antix.

Or disable suspend, maybe hibernate will work!

It could be lack of kernel support for the Radeon graphics device. MX 21 used to work. Any uses with retrograding to that version?

It's already light-locker ootb.

You can install 4.19 and 6.1 kernels from "MX Package Installer" , boot with and try. (4.19 and 5.10 will be in Advanced Options on Grub menu after installation.)

Posted: **Sun Jun 18, 2023 9:17 am**

I tried the other kernels but no luck. I tend to think the problem relates to memory going into swap (cache?). Any ideas on configuring? Swap size should be ok at 8GB.

Posted: **Sun Jun 18, 2023 10:54 am**

Your swap is more than enough:

swap-1 type: partition size: 11.72 GiB used: 0 KiB

Memory: 5.8 GiB used: 1.84 GiB (31.7%)

We can try to create a resume file, what's the output of this?

Code: Select all

lsblk -f | grep swap

Also what happens if you suspend with this one?

Code: Select all

sudo pm-suspend

Posted: **Mon Jun 19, 2023 9:59 am**

From the lsbk command I get
├─sda3 swap 1 swapMX e75c0c7f-7643-4d87-9391-0c2360e101a5 [SWAP]

Unfortunately the command line suspend also leads to the same video problem.

Appreciate the help!

Ok, at least now we know that it's not a light-locker issue.

Code: Select all

echo RESUME=UUID=e75c0c7f-7643-4d87-9391-0c2360e101a5 | sudo tee /etc/initramfs-tools/conf.d/resume ; sudo update-initramfs -uk all

Reboot.

Though this may/may not solve this issue, no harm.

Posted: **Mon Jun 19, 2023 11:21 am**

Dang! I still get the bad screen after suspend... thanks for the suggestions so far...

Posted: **Mon Jun 19, 2023 11:23 am**

Ok, then , can you still use the terminal and do 1-2 things? Though the screen looks bad...

Code: Select all

inxi -Gaz

when that happens and let's see how it looks at that moment.

Posted: **Mon Jun 19, 2023 11:29 am**

This is going to sound really odd, but lower your screen res to something under that 1680 and try the suspend.

If it works ok, then you may have an issue with the driver and refresh rate on that iMac.

Posted: **Mon Jun 19, 2023 1:24 pm**

Here's the inix output. just after suspend (screen still bad)

I tried the suggested screen res change but it didn't fix the problem....

Posted: **Mon Jun 19, 2023 1:38 pm**

This is really weird cause everything looks normal, drivers are ok and the res.. so, we can try just to turn off and on ..

When that happens try (if one doesn't work, go on with the next one):

Code: Select all

xrandr --display :0 --output LVDS --auto

Code: Select all

xrandr --output LVDS --off ; xrandr --output LVDS --auto

Code: Select all

xrandr --output LVDS --off ; sleep 1 ; xrandr --output LVDS --primary --mode 1680x1050 --rate 60

Posted: **Mon Jun 19, 2023 1:44 pm**

Do you mean to try these commands and then go into suspend, and see if it's normal afterwords? Or try these when the screen is not displaying properly?

Posted: **Mon Jun 19, 2023 1:46 pm**

Yep, just when that happens after a suspend & wake-up (to see if any of them works).

Posted: **Mon Jun 19, 2023 1:54 pm**

I tried these. The second and third ones causes the screen to go back briefly but came back again with the resolution problem. The first one didn't do anything noticiable...

Posted: **Mon Jun 19, 2023 2:04 pm**

Ok. In fact I remember a very similar one, again with radeon, again with a reddish screen etc... The verdict was that it was a hardware problem.

In this case (what we did) It turns off and turns on with the wrong resolution even when we state what it should be (the 3rd one) , and though it shows the resolution and drivers are already ok ...

Posted: **Mon Jun 19, 2023 2:08 pm**

OK, got it. It did work fine with MX19 though. But it's not too hard to just avoid using Suspend. Thanks

Posted: **Mon Jun 19, 2023 2:10 pm**

Ah, ok, I was just writing this:

The only thing I would try:

Is it the same if you try any other distro on live session?

______________

However the main difference (with MX19) is the 4.19 kernel, that you already tried ... Then maybe others are affecting, mesa version etc...

Posted: **Mon Jun 19, 2023 2:12 pm**

OK, I can try the MX19 live USB.... will report....

Posted: **Mon Jun 19, 2023 2:14 pm**

Ok, but since you already know it was ok there, you can skip that if you like ...

Posted: **Mon Jun 19, 2023 2:37 pm**

Well it actually didn't work with MX19 live disk. Corrupted video just like the current version. I recall when I was installing Linux on this Mac three years ago for the first time, I had trouble with most distros. They had the suspend/wakeup issue. I was able to get MX Linux to work properly, I think by doing something with the partitions on install. But I don't remember what the trick was :(

Posted: **Mon Jun 19, 2023 3:36 pm**

Since it's a desktop, have you tried with another type of connection? DVI etc.. Or playing with cables when that happens, unplug and plug ...

Posted: **Mon Jun 19, 2023 4:02 pm**

It's an all-in-one mac so no connections. I think I will move away from Macs (for Linux systems)!!

Posted: **Mon Jun 19, 2023 4:05 pm**

Ah, ok, I was asking myself why it was LVDS :)

Posted: **Mon Jun 19, 2023 4:12 pm**

Thanks for your help and suggestions!

Posted: **Mon Jun 19, 2023 4:41 pm**

You're welcome, I wish they worked.

Since the resolution, drivers etc. look ok when that happens, it seems the card is ok, just there's something with the monitor (it can't display correctly what the card outputs..). So, if it was an external monitor, playing with cables would work imho.
