Ubuntu works very well on XPS laptops, but it is not so easy getting the laptop to boot from a USB.
Step 1: Change POST Behavior from “Fastboot” to “Thorough”
- At boot, Press the F2 key (or alternately press the F12 key then select the option to enter the BIOS setup).
- In POST Behavior, Select – Fastboot the select the Thorough option.
Step 2: Put USB in the right USB Type-C port
This is the main trick I have been unable to find documented anywhere else. The BIOS only recognizes bootable media in the right USB port.
- Create bootable Ubuntu USB (Or any other linux distro)
- Put USB in the right USB Type-C port. Only the right USB port will be detected in the boot options.
- Reboot the system, press F12.
- Select your USB in the boot options.
I had this problem on a my new phone. Found the solution on a T-Mobile forum but it was difficult to find. This post is to link back to the correct solution so it’s easier to find and to save the correct solution:
The problem has to do with the phone’s APN settings – which need to be tweaked.
1. Access your Android phone’s settings (gray settings icon that looks like a gear).
2. On the settings menu – select “Network & Internet”
3. On the “Network and Internet” menu – select “mobile network” (which should say “t-mobile” beneath the words “mobile network”)
4. On the “mobile network” menu – select “Access Point Names” (often abbreviated APN).
5. On the “APNs” menu – you should see two options: “T-mobile US” and “Tmobile MMS”. There should be a green dot next to “T-Mobile US”. Select that “T-Mobile US” option (NOT the Tmobile MMS).
6. This will open an “edit access point” menu, and you will need to make the following edits:
First – click on the MMSC option and add the following text: mms.msg.eng.t-mobile.com/mms/wapenc
Second – click on the “APN type” option. It will probably say something like: “default,supl,hipri,fota” (without the quotation marks). You will need to tweak the end of it so the whole thing instead reads “default,supl,hipri,fota,mms” (without the quotation marks). As indicated here – there are no spaces between these commas.
Third – after making these two adjustments to your APN – make sure you click on the menu dots (three vertical dots) at the top right hand part of the “edit access point” menu. This will open up a drop down menu – and then you should select “Save”. If you don’t do this – the settings will not take effect.
