  1. Looks like ALL the recent thinkpad models have this issue, sadly. Other people confirm the same... It's a shame
  2. First of all let me explain my home network setup. I have this 5G Modem that connects to the internet on a remote place, a ZTE MC801a with internet speeds up to 600Mbps of Download and 60Mbps of upload, with 2x 1 Gbps RJ45 ports On this modem 10m further there connected this "chinese" unmanaged switch, with 4x 2.5 Gbps ports + 2x SFP+ 10Gbps Modules. The switch has 3 ports used and is the main access to the entire network. The ports used are three, two of the 4x 2.5Gbps and one of the 2x SFP+ 10Gbit ports: - 2.5 Gbps RJ45: My 2.5Gbps PC network card - 2.5 Gbps RJ45: My 2.5Gbps access point - 10 Gbps SFP+ RJ45: My 1Gbps negotiated 5G modem with 10m of cat5e cable Long story short, ONLY with my desktop PC, and ONLY when the modem is connected to one of the two 10Gbps SFP+ ports, the upload speed tests are somehow capped at 20Mbps rather than 60Mbps only from that desktop. Download looks normal. The funny thing? Negotiating manually the speed of the PC from 2.5Gbps to 1Gbps on my desktop, the upload speed goes back to normal. I have tried the following: - Connecting the modem to the RJ45 2.5Gbps port, the issue is fixed - Trying different OS, issue present on both Linux and Windows - Trying a speedtest from the 2.5Gbps AP, issue not present here. - Resetting all devices - Trying to change ethernet related power saving flags Since those SFP+ modules are expensive, I'd like to know what the hell is going on... I can't really even remotely figure out the issue here. It could be a compatibility problem with the PC network card and the router, but only when the switch is connected with the SFP+ 10Gbps port to the modem... Other devices do not have the same issue. Still, doesn't make any sense. I also tried shorter cables, the ethernet cables going to both PC and modem are 10m long each other, and the upload speed to other devices in the network are just fine. I tried putting a laptop which has a 1gbps nic like the modem, with iperf on the SFP+ 10Gbps port and the results look normal.
  3. Basically I always used trackpoints on all the thinkpads I owned, x60s, T440s, X1 Carbon gen 3, X1 Carbon gen 4, and never had any single issue with the Trackpoint until I bought an used T490 The issue I am having is the worst click feedback ever, skipping text when selecting it, or even scrolling with the middle click pressed casually skipping and copy-pasting things (I use Linux, but the same happens on Windows), to make it work properly, you have to press REALLY hard. Never happened even on a 15 years old x60s, when you feel the click feedback, it just works! Since it was used, I thought it was the keyboard fault. I tried 3 different keyboards, all with the same problem. I ended up buying a 100€ original Lenovo keyboard, still having the same problem. See the video so you can understand what I mean I watched different videos thinking I may be doing something wrong when installing it, but I'm not. The screws are tightly in place, tried with loosing the screws or even putting some tape under the buttons, no change. Since I'm a really serious Trackpoint user, my entire usual workflow with the laptop is ruined. I don't use any external mouse and the trackpad sucks on anything that isn't a macbook. I am really thinking about returning it and buy something else. video_2023-12-07_18-04-03.mp4
  4. I think that's good, but a correct comparison would be using DXVK/VKD3D even on Windows, but thats not always possible without breaking the desktop. Neverthless, AMD is doing a great job in the linux graphics ecosystem speaking of kernel drivers, vulkan implementation, and the support overall so I won't be surprised on the same machine to perform better. At least on a full AMD build Still lacking on some nitpick things like eGPUs
  5. Because when the graphics works, you will never see those ACPI messages (too much fast)
  6. Probably a graphic drivers issue. This needs further investigating the system logs, install rsyslog and check the /var/log/kern.log after the issue happens for the full record. You just see the ACPI on screen because they take priority for some reason, the real culprit is the GPU probably
  7. I can't understand the environment Same OS version on those servers? Multiple physical servers? Virtualized?
  8. Used liquid metal. Temperatures less than 80c°, slighty worse for the GPU but whatever. Problem "solved", hope it lasts.
  9. you are not running x86_64 qemu first of all, you should tell us what packages you have installed
  10. Yeah, it is in setup mode. You have to install the factory keys, go into key management and choose something like that, it shouldn't be in setup mode anymore.
  11. Changed my mind, worth trying liquid metal. I’m sick of it. I spent literally half the price I paid for this so I don’t care if I break anything else anymore, my only issue is how and where to apply the conformal coating, if any, and how to prevent liquid metal from slipping out of that heat sink. Also, I may use it only on the CPU
  12. yeah I double check them by pressing by the finger and making sure they are tightly screwed, not too much because I would probably strip the screw or the screw hole
