M4800 Owner's Thread

Has anyone found acceptable settings for the touchpad on Linux? Compared to the Windows driver I find that the thing is unusable, I effectively have to rely on an external mouse

 

Years ago I used ("xset m 5 1" in terminal) on both thinkpad and dell but now that every distro has adopted Wayland to replace Xorg this command does nothing.
I've pointed out the issue and had some suggestions but this included editing an array of random seeming eventXX files which you have to find out which is which (mapped to) with "libinput list-devices".
We did a bit back and forward tests with values but nothing was as good as "xset m 5 1".
Adjusting the acceleration and etc is a whole science that is either too much or too little and it became such issue that I had to use a multiplier and decimal to get closer my goal but that made the config to be ignored on login, mind this was years ago just weeks after wayland was being pushed out and I reached out to find help due to me being depended on my trackpoint.

The specifics to how to setup and debug this is up to what distro you are running.

I may also mention that I use a 3D printed adapter on my trackstick to fit a Lenovo trackpoint "soft rim" cap on there which greatly improves the ease of use and precision in pointing compared to Dells original black and the blue and black cap.
I ordered several of them to fit on all my Dell laptops.

Touchpad is just as bad in my opinion, its so bad that I don't even use the touchpad and resort to using a mouse.
One reason this sucks, is that both the trackstick and touchpad is made by Alps compared to synaptics on thinkpad and other brands

Dell has one article but its 1 outdated because ubuntu now uses wayland since 21.04 and not Xorg and 2 it include steps for synaptics which it does not have

....so that's useless information

 

Such a shame, may have to look for a Mogo mouse X54 then. Playing around with it is a bit too much in my opinion and I'll just stick with an external mouse then

 

I tried to mod it myself with the editor but it resulted in instability with what I thought would work. I have reverted to the stock one, due to the fear of damaging the card...

 

New MXM GPUs coming out. RTX A2000 (3050 Ti mobile equivalent) will be beastly in the M4800 if it turns out to be compatible.

8GB in MXM-A? That'd be nice to have, if it works of course.

 

The new card is using DDR6 though. Not sure if that will work on old M4800 system.

I decided to not bother with anything beyond M5100.

I've tried WX 4130 card and it didn't work well. It caused black screen.... I've tried deleting and re-installing the driver for 10 hours and decided to give up. Let's not bother with anything that Dell originally provided. I rolled back to M5100 and now everything's ok.

I mean GPU card upgrade isn't for every OS and system.

 

The WX 4150 or M2200M is the best you can get with some tweaking involved.

 

How stable is M4800's SD card slot?

I found this SD card adapter that is exactly in the size of Dell's SD card slot.

It will fit just like Dell's original blank filler card:

I'm planning to add a 512GB micro SD card from Samsung to the adapter.

I'm curious if the SD card will work just like regular HDD storage for daily use? if this works out, then the sd card slot can be the 4th storage of M4800. There are 1TB micro SD cards on sale.

 

Hello, it works GREAT. Nvidia Quadro T1000 on M4800 with the newest drive 472.47.
It is easier than what I thought. No need to modify the .inf file.
Just manually select the nvadwi.inf driver file, than the driver can be installed successfully.


Hardware Spec:
M4800 is Gen2 with LCD,15.6FHD,IPS,EDP1.3,AG,AUO
Graphic Card is Adlink EGX-MXM-T1000 with the original AMD heatsink module (Nvidia one is not possible)
