OpenBSD 7.6 on a Lenovo T490
Here are my notes on installing OpenBSD 7.6 on a Lenovo T490 and why I'm happy.
I've been running NetBSD 10 on a PineBookPro for several months and it served me well as a home lab laptop for various chores. That is until it literally split in half! Yes, a back panel screw mount slowly wore out and one bad day I opened the lid and heard a cracking noise and smelled "magic smoke". The metal hinge on the same side was not seated correctly and had enough leverage to do some damage to the remaining mounts. Here's a photo of the tragedy.
In need of a replacement lab laptop, I decided to give a used Lenovo AMD64 device a try. I found some notes online on support in NetBSD 10 and FreeBSD 14.x. I also found many posts on running OpenBSD 7.x on a variety of models.
Ultimately I found a $200 refurbished Lenovo T490 online, with 8Gb ram, an 8th gen i7, 1080p display, and 256Gb SSD. This looked like a good model for OpenBSD 7.6
Installing OpenBSD 7.6
The laptop came with Windows 10 installed and a 1 year warranty. I booted Windows 10 and made sure all the hardware checked out -- looked good. Cool, now time to get Windows off and OpenBSD installed.
I followed the official OpenBSD installation Guide. As with BSD documentation generally, it is thorough and well maintained. I downloaded the amd64 install76.img image and copied to a USB memory stick.
First, you need to boot to BIOS and make sure Secure Boot is off. OpenBSD supports UEFI so I kept the remaining default settings, saved the changes, and restarted. Pressing ENTER on startup allowed me to select the inserted USB stick from the boot menu, and the OpenBSD installation began.
I chose full disk encryption on the SDD drive. Since it's a laptop I use for my home lab, there are several SSH keys and secrets I do not want lost along with a stolen laptop. I went with a passphrase, but you can also use a keydisk.
The OpenBSD installation is straight forward (even the disk encryption part). I rebooted and was pleased to see X prompt me to log in. Everything looked good on first boot.
Hardware
I'm happy with the hardware and everything I need in a laptop works for use around the house and the occasional trip outside (easily tethers to my mobile phone Wi-Fi).
- Suspend works when closing the lid.
- The Wi-Fi
iwmdriver supports 5ghz and is stable; Ethernetemdriver works well. - The touchpad is good and tap and two finger scroll work; trackpoint works too.
- The keyboard is the usual good quality Lenovo and volume and brightness keys work.
- Good USB support.
- SD card slot works.
- HDMI output works on my external monitor.
- The Intel video driver is solid and streaming video on Firefox is suprisingly good.
After a few days of use I was convinced I was going to like this laptop, so I decided to upgrade the RAM from 8Gb to 24Gb. The existing 8Gb is soldered to the board but there is a free RAM slot. I ordered a $30 Crucial RAM 16GB DDR4 3200MHz CL22 CT16G4SFRA32A SoDIMM. Installation requires unscrewing the back panel mount screws and carefully using a pry tool. There are videos etc online, pretty standard for a Lenovo RAM upgrade. With the increased RAM, [0] dmesg and [1] hw.sensors below.
Configuration notes
There are a few configuration changes I made. For the touchpad, I added settings in /etc/wsconsctl.conf to make adjustments to two finger scrolling and to enable tap:
mouse.type=synaptics
mouse.reverse_scrolling=1
mouse.tp.tapping=1,0,0
mouse.tp.scaling=0.165
mouse.tp.edges=0.0,5.0,0.0,5.0
This reverses the default scrolling to what I'm used to (aka "natural" scrolling). I enabled single tap, but disabled two and three finger taps which I don't use and instead use the touchpad buttons.
I didn't change anything to the X configuration yet and I'm still trying different window managers (default is fine too). Generally, X support is good, with Firefox and Thunderbird all running well.
The video camera works and to enable you need to set kern.video.record=1. I placed this in /etc/sysctl.conf.
The battery life is looking reasonable and I'm still tweaking power settings. I added amd_flags=-A to /etc/rc.conf.local.
Summary
My 2019 refurbished Lenovo T490 feels solid and I am happy running OpenBSD 7.6. It's good to have a BSD laptop back in the lab!
