Slimbook for Linux: KDE's hardware partner, with one nasty bug
Slimbook is the vendor KDE chose for the official KDE Slimbook, and the one most people in southern Europe reach for first because it ships from Spain. The Linux support is good. There is one documented suspend bug on the Executive line that the store page will never mention, and it is the reason this page exists.
Who they are
Spanish company, Valencia area, building Linux laptops and small desktops since 2015. They ship from inside the EU, so for an EU buyer the price you see already includes VAT and a return does not cross an ocean. They are the hardware partner behind the KDE Slimbook, which gives them a direct line into Plasma testing that most ODM-rebadge vendors do not have.
What they ship
Slimbook OS, an Ubuntu base, or your distro of choice preinstalled, plus slimbookbattery and slimbook-tools for power profiles, battery charge limits, and keyboard backlight control. KDE Slimbook units ship Plasma by default and that combination gets real upstream attention. No full coreboot story like System76, so this is a support-and-tuning vendor, not a firmware vendor. Set expectations accordingly.
Most of the lineup runs Linux well out of the box because, like Tuxedo, they choose supportable parts. The Pro X and the lower-tier base configs are the safe, boring picks. The Executive is the one with the asterisk.
The catches the store page skips
The Executive has a documented plugged-in suspend bug. This is the one. Dedoimedo’s hands-on review of the Slimbook Executive documented suspend failing while the laptop was connected to AC: lid closed and plugged in, the machine would not stay asleep correctly. On battery, suspend behaved. Plugged in, it did not. That is a specific, reproducible, published failure (see dedoimedo.com, Slimbook Executive review), not a vague forum complaint. If you dock the machine at a desk on AC and expect lid-close suspend to just work, test that exact scenario on day one and use the return window if it does not. Firmware revisions may have changed behavior since, so verify against your unit rather than trusting the spec sheet.
The software stack is theirs, and lighter than Tuxedo’s. slimbookbattery does the basics. It is not as deep as TUXEDO Control Center for fan curves. If you want granular fan control out of the box, you will be reaching for fancontrol or similar yourself.
Stock-and-region availability is uneven. Configurations and shipping times from Valencia vary more than from a larger vendor. Not a Linux issue, a logistics one, but it affects whether you can actually get the model you want when you want it.
Who should buy
EU buyers, especially in southern Europe, who want strong Plasma support and in-region shipping and RMA. The Pro X and the base configs are the low-risk choices. If you want the Executive, you can still buy it, just test plugged-in lid-close suspend immediately and keep the return window open until you have confirmed it on AC, because the documented bug is real and battery-only testing will hide it.
Slimbook does not currently have a model tracked in our database, so there is no model page to link yet. Treat the vendor advice here as the takeaway and check the Executive’s suspend behavior against an independent hands-on review before you commit.
FAQ
Is the Slimbook Executive suspend bug fixed? Dedoimedo’s review documented suspend failing on AC while it worked on battery. Whether a later firmware fixed it depends on your unit. Test lid-close suspend while plugged in on day one and do not rely on battery-only testing.
Why buy Slimbook over Tuxedo? Closer shipping for southern Europe and a direct KDE Plasma testing relationship. The tradeoff is a lighter control-software stack and more variable stock.
Do they ship from inside the EU? Yes, from Spain. VAT is in the listed price and returns stay within the EU, no US-style import charge.
