How much do you like the 4K OLED? Looking at youtube videos, it seems quite glossy. Does it compensate for that with high enough brightness? Are you able to use it outside or if there is some light behind your back? Is the touchscreen working with linux? Thank you for any insights on this.

Is this true for the 7670 OLED as well? Because multiple articles on the net say that OLED brightness switching is "mostly" done by PWM and there is visible vibration with low-brightness setting.

1. Do we have any info on when will models with DIMM and interposer be orderable? 2. Does an OLED display have a "background light" refresh rate? (I know there is no background light, I mean how is dimming implemented in the hardware). Eg if someone is irritated by PWM'd backlight with non-OLED displayed, does OLED solve this? I mean are the individual LEDs brightness controlled by PWM also or is do the LEDs always stay on and the brightness is controlled by the current to each LED? Googling the OLED PWM issue, there are a few threads about this, eg @Dell-Mano_G Can you share some specs of the OLED display in the Precision 7670? Eg could lower-brightness PWM be an issue?

Yes, there is a Dell repo, but in practice I was not able to use it, because the packages are strangely named, you don't really know what is for what, run into dependency issues, etc. There are also Dell WIKI pages for Ubuntu if you search inside the Dell support pages, which is somewhat helpful, but again not up-to-date, may not apply to your model, etc. A good resource is Arch linux Dell pages with some details on what works and what not (eg see the Precision 7760 to see what "magic" issues I'm talking about).

Most likely the support is on the same level as Dell's, but there were/are good WIKI pages about how things work. Eg how to change display brightness, how to access various registers that show the battery levels, and many small things. Also, it would be good if you could just install a stock Ubuntu and configure a Dell repository to make things work. If that's too hard, at least make the technical details available, so everyone can configure stuff on his/her own. Also, I do not expect level-1 support to be proficient at Linux, but if you have a real problem, I'd expect that level-1 can put you into contact with a Dell engineer that is knowledgable and can give specific info (or even better, document it for everyone else).

Hi, Thanks for reflecting on each point. Just some replies: 3. Yeah, it seems 😞 I find these improvised keyboard changes mind-blowing. Home/End/PgUp/PgDown/F11/F12 is basic functionality, even for someone who is just doing word processing, but even specialty applications use them. Also, why the heck mess up the numeric keyboard's calculator buttons and wire them together with F6 and such? I guess this could have been solved in software, so everyone using Windows' calculator is happy, while everyone using something else can use buttons for whatever. Could be a BIOS setting as well to switch between these modes of operation. 4. Yeah I have no doubt that Lenovo support staff is also not knowledgable, but at least for Thinkpads these used to be quite good WIKI pages and community support. For example, when Dell ships a notebook with Ubuntu, they install some custom Dell packages, that "make things work". For example make sure that the display brightness buttons work. However, if you install another distribution or just re-install ubuntu, these are no more available and there is no technical description anywhere, how it is working technically or where to get the custom Dell package. There are a lot of messy details like display brightness, Nvidia Optimus to switch between integrated and dedicated GPU, fingerprint reader, webcam, etc. I have no hands-on experience with recent Thinkpads, but the P16 may be better in this regard. Also the keyboard layout is way better, all the keys are present and located where god himself has put originally. I guess less SSD slots in the P16 is a downside, and also no CAMM (It says "Up to 128GB DDR5 4800MHz (4800MHz native, 4000MHz actual)" on the website). Also I have 3-4 Dell chargers which would go obsolete with the P16. I also wonder, if P16 gives a better docking experience or not. The recent Dell docking stations were not really supported by Linux (it worked for an hour, then shut off the external display). 5. It seems there is less and less we can replace, which was the main selling point for enterprise-class notebooks. The RAM we most likely won't replace due to CAMM, WWAN you just have or not have. Keyboard/Fan maybe interesting later on when there is no warranty any more, but these I guess harder to replace now. So it's basically the SSD which is left..

Hi! I'm also considering buying a 7670. Some questions: 1. Is there finally a Geforce option or not for 7670? (I guess it requires a perf. chassis) 2. What's the pro/con for going with camm or SODIMM for the same memory size? (64GB for me) 3. Do you think the keyboard layout of the 7x40 ever comes back? (in the next generation) Full sized arrow keys, home/end, pageup/pagedown? 4. What are the pros/cons compared to Lenovo P16? That has a proper keyboard and probably better linux support (I've found Dell's linux support to be extremely weak - their support guys are simply clueless about linux and many hardware components, eg fingerprint reader are simply not supported - maybe I was unlucky but that's my first-hand experience. Oh, and if you order with Windows, they won't support you with linux!) 5. What are uses-replaceable parts? Eg keyboard/SSD/RAM? Thanks everyone!
