In R4.1, X was automatically using the modesetting driver and I observed some visual artifacts when dragging window or scrolling through Qubes Manager VMs.
I forced it to use the intel driver and those artifacts went away. Even with X using the modesetting driver, 1080p Youtube videos still played fine (though high CPU) and the artifacts were not observed in playback.
Improving battery life, frequency scaling, and power management will take some investigation. I’ll have to do more R4.0 vs R4.1 back-to-back investigation, but it appears under R4.1 battery drains a little faster when idle.
With sys-firewall, sys-net, sys-usb running, I can use 2-3 other qubes comfortably with 4G of RAM (but see the memory limiting stuff I mentioned above in the first post).
In my experience the only places where you get a “win” on being able to add more RAM to a laptop than the laptop specs state is when a) the CPU supports larger RAM than is currently available on the market or for manufacturer certification and b) the manufacturer writes support for the RAM size into the BIOS (but, again, cannot test it to certify it).
The x230 has only a pair of RAM slots, and the CPU only supports 8GB per.
This is one reason that the era’s W-series are so useful w/ Qubes: they have four slots to support the era’s quad-core CPUs and therefore can support 32GB. Note there are a few W-series that are dual core an that are also limited to 16GB.
Flashed BIOS to latest 2.82 (21 Aug 2019) before install
Qubes settings: default OS changed to Debian, all other defaults kept
installation successful, no problems, everything tested works normally
Tested and verified, works normal, no fix needed:
track point mouse
usb port (connected mouse)
usb port (connected external SSD)
audio + audio control buttons
memory card slot
I was extremely lucky and got a “new” (aka unused) T430 that spend the last 10 years in original packaging at an IT warehouse. After upgrading it to make it identical to the one I already have, I installed R4.1 on both of them.
This machine is the best and it certainly works flawlessly without any workarounds or troubleshooting with R4.1. This being said I have a couple of notes I want to share:
If you use Coreboot/Heads make sure you upgraded to the current version Heads-v0.2.0-1150 or the install won’t work.
dom0 needs zenity installed for things like qvm-move-to-vm to work. Also in case you want to use Whiskermenu one now has to install xfce4-whiskermenu-plugin which was included by default previously.
Most of the Qubes OS UI in dom0 is now Qt5 based and doesn’t by default adhere to the selected theme, which is especially annoying when using a dark theme. Luckily this can easily be remedied by installing qt5-qtstyleplugins and exporting QT_QPA_PLATFORMTHEME=gtk2 (e.g. in /etc/environment).
I get a very noticeable performance bump when using Btrfs as opposed to whatever is the default. I don’t have the technical understanding to explain this but I have done repeated A-B-A experiments on two identical computers and at least with my exact hardware (see above HCLs) the difference is very noticeable. This was the case with R4.0.4 and subjectively is even bigger with R4.1 (e.g. due to the current world situation I have a qube permanently streaming CNN in a window on my screen… this was not fluid and somewhat bumpy in the default install but runs smooth as butter now with Btrfs – I know that doesn’t make sense on the face of it, but it is what I see; also general qube startup times are several seconds shorter) … so I continue to strongly recommend this for this machine.
I’m looking to get a T430 (from Nitrokey) and I can see quite a few here have experience with a T430. I’m not well versed in laptop hardware, but does the Atheros AR9462 work alright with the T430 and with QubesOS? I’ve got the option to choose between the Intel 802.11b/g/n 2200N and the Atheros AR9462 (for a small additional price), but I’m not aware of the differences between them.
Hi @anon23935512 there is no special recommendation for just the T430. In general the use of an high quality SSD is recommended. Do a little research about their specs and then choose one that fits your budget.
Personally I am using the Samsung 860 PRO 1TB 2.5 Inch SATA III SSD and are very happy with it. In my own experiments I found that my T430 performs a lot better if I use BTRFS instead of the default option. Especially with R4.1. However, I cannot explain this or guarantee that you will see the same performance boost I see. I did confirm it with multiple installs on two different T430’s.
